String variable of Unicode characters problem

Hi all
I define a variable named "vRemoteParty" ... with String type
in order to store the return value of "7748"
I got the following result via the UCCX debugger ...
Result: U"\u3737\u3834"
suppose it is result: 7748 ...
So. how can I convert this unicode character in UCCX script??
I tried the String.valueOf() but seems not working
Anyone could help
Thanks
Sam

I found that the problem only existed while connected to MySQL database
The STRING returns correctly if querying with Microsoft SQL.
Does it mean the UCCX does not support MySQL??
or there is any setting should be changed in MySQL or UCCX
Thanks
Sam

Encode/Decode a String containing Chinese etc. characters to/from unicode

Hi, I am working to encode a multilingual String (English, chinese, japanese, Latin etc) as unicode. The encoded string is used as follows
1)decoded by the User Interface for display purpose. The user interface is a web UI and
2)read by user. So it should be human readable when it contains only English and special characters.
Thus having a string that contains letters from English, Japanese, CHinese etc, we want the Japanese/Chinese characters to be encoded by the hex values such as 私 be encoded as %E7%A7%81.
However, it is preferable that other special characters like ! ? , space etc not be encoded and left as such.
The encoding of characters is achievable by using Java.net.URLEncoder but it also replaces all special characters including space character, which becomes a pain for the reader.
Unfortunately URLEncoder.java does not have any API to configure which characters to encode. Any suggestions how I can proceed, or what encoder i can use?
Thanks in advance!
Regards

I have to say that I disagree that "%E7%A7%81" is "human-readable". On the contrary, I would say that "私" is human-readable; even though I don't understand it myself, there are a lot of humans who do.
But let's say that "human-readable" wasn't the right term. Maybe you just wanted a representation of an arbitrary Unicode string in ASCII characters only. In which case I would recommend Base-64 encoding. It does make everything unreadable, though, whereas your requirements appear to be to only make languages other than English be unreadable. So if you don't like that you are going to have to write your own encoder.
Note also that your original premise:
Hi, I am working to encode a multilingual String (English, chinese, japanese, Latin etc) as unicode.is misguided, since all data in Java Strings is already Unicode characters.

Replacing Unicode characters in a String

I have a text as a String and in this text which is foreign language appears sometimes characters in Unicode format as &#246; or &#214;
The question is, how can I convert this String so these Unicode characters would become readable characters.
Thank you for any lead...

:-) Interesting - twice in 10 minutes I'm recommending the use of Elliott Hughes' class. See http://elliotth.blogspot.com/2004/07/java-implementation-of-rubys-gsub.html .
You just have to write a regular expression to match the terms ( "&#(\\\d+)"), extract the number as a string (group(1)) then use the Integer.parseInt(the numeric string) and cast to a char.

This is an example I wrote a couple of years ago (and published on the old Sun site forums) that does pretty much exactly what you need
import e.util.Rewriter;
public class Sabre20090919
    public static void main(String[] args) throws Exception
        String title = "& #26412;& #26399;& #28136;& #21033;\n" +
                "& #22522;& #26412;& #27599;& #32929;& #30408;& #39192;\n" +

                "& #26222;& #36890;& #32929;& #27599;& #32929;& #30408;& #39192;\n" +
                "& #31232;& #37323;& #27599;& #32929;& #30408;& #39192;\n";
        Rewriter rewriter = new Rewriter("&\\s*#(\\d+);")
            @Override
            public String replacement()
                return Character.toString((char) Integer.parseInt(group(1)));
        title = rewriter.rewrite(title);
        System.out.println(title);
        System.out.print("Unicode :\"");
        for (char ch : title.toCharArray())
            System.out.printf("\\u%04x", (int) ch);
        System.out.println("\"");
        byte[] asBytes = title.getBytes("big5");
        for (byte b : asBytes)
            System.out.printf("%02x ", (int) (b & 0xff));
        System.out.println();
}The rest is just a test harness.

Problems reading unicode characters with BufferedReader or PrintWriter

I am creating a pretty standard chat server and client with the exception that I want to be able to send special math symbols back and forth to aid in helping people with math homework. The unicode characters will appear on the buttons, in the textField (where users type in their messages), in the messageArea (where users see all of the messages) correctly. However, as soon as the server reads it, it is converted to a ? character by either the BufferedReader or the PrintWriter, but I am fairly certain it is the BufferedReader. All of the Sun examples I have read recommend doing exactly what I have done to be able to support unicode characters so I am somewhat at a loss. Any help would be appreciated. I will include all of the source code (which is rather large) but the main problem is the with the BufferedReader or PrintWriter when the servers reads the string in and then broadcasts it to all the clients (at least I'm pretty sure it is).

Yes, the code is large, isn't it. It is a good idea, when you have a problem you can't solve, to remove unnecessary code. When the problem disappears, then you know the code you just removed was probably the source of the problem.
But in your case, I think that none of the 1000 lines of code you posted are the problem. You appear to be using Lucida Sans, which is a positive sign; it can render many of the characters you have hard-coded in your program. But apparently the problem is with characters that are coming from somewhere else? And you are using a PrintWriter to send them there and a BufferedReader to get them back? These convert your data from characters to bytes and back again using the default encoding for your system. Chances are that this encoding is some "extended ASCII" encoding that doesn't know how to map anything above \u00ff. You need to get an InputStreamReader and an OutputStreamWriter into your transmission. (Wrap your socket.getInputStream() in an InputStreamReader and wrap that in a BufferedReader, etc.) These objects can take an encoding name as their second parameter; try "UTF-8" or "UTF8" for the encoding. Their API documentation has a link to a page about encodings; follow that if you need more info.

Problem with String variable

I am new to Java Programming.
I have a line of code that works and does what is supposed to.
faceData.getProfile("Lisa").removeFriend("Curtis");
If I assign the strings to variables such as-
String name = "Lisa";
String fName = "Curtis";
and then plug those into the same line of code, it does not work
faceData.getProfile(name).removeFriend(fName);
What could be causing the problem?
I even added some lines to print out what is stored in the variables to verify that they are what they should be, but for some reason the variables do not work while putting the strings in quotes does. Any ideas?

I guarantee that something about your assertions are incorrect. Those variables are either not equal to the values you claim, or something else is going on. But it's not a problem with string variables versus string constants.
Edit: My best guess in lack of a real example from you, is that the strings in question have non-printable characters in them, such as trailing spaces or line feeds.

Maximum number of characters for a BPEL string variable

Hi,
What is the maximum numbers of characters that a string variable in BPEL process can hold??.
Is there any document which describes the datatypes in BPEL.

Trick question - with or without the use of the FM GUI?
1. Via the FM interface to define a variable, FM will only save the first 1022 characters of your variable definition - if you dare try to enter that many via the GUI dialogue slot.
2. Importing a variable via MIF, adds virtually any length - I've tested out 2510 characters. HOWEVER, FM will only display the first 1023 characters of this string.
If you save the file to MIF, you can still see the original length of the variable. The other caveat is that if you touch any of these long variables via the FM GUI (Edit Variables), then FM will truncate it down to 1022 characters - regardless of how you save (binary or MIF).
FWIW - Klaus Daube lists (see: http://daube.ch/docu/fmaker25.html ):
Until FM 7.2: up to 255 characters including meta-notations (such as <Default ¶ Font> or \t - this counts as 16 resp. 2 characters). See also note Variables below
From FM 8.0: up to 2023 Windows Codepage characters or up to 2022 UTF-8 characters
I'd say that this is not quite correct. You could enter more than 255 prior to FM 7.2 as well, but again the display issue via the GUI kicked in and truncated down to 255. The newer versions only display 1022/1023 but you can enter more than 2510 characters (which in this case is futile anyway).

Is there a limitation of characters in a String variable in 8.0.2?

Is there a limitation of characters in a String variable?
I'm trying to create an email within my script and when I paste my text into my parameter, which is a String variable, it will only paste up to 80 characters (including spaces).
In 7.0 I was able to paste my paragraphs and the larges paragraph had 346 characters (including spaces).
Thanks,
Debbie

Greg,
Ah.... that's it.
I modified the value of the parameter within the script and added the text that I needed. I added the following:
"To transfer the file over to the router's flash you will need an TFTP or FTP program. Start your application and make sure that the default directory is pointed to the directory where you copied the greeting. Now log into the router that needs to be updated. Once you are in the router issue one of these commands:"
It accepted it and was able to use the entire value. So it must be the web page that will not allow me to enter more then 40 characters.
Do I need to get this submitted as a bug?
Thank you,
Debbie

Special characters in String variable sent from php.

Hello. Assuming that I send some String variable from php into flash:
AS3:
var MyImportedString:String;
var variables_page_text:URLVariables = new URLVariables();
var varSend_page_text:URLRequest = new URLRequest("MyPHP.php");
varSend_page_text.method = URLRequestMethod.POST;
varSend_page_text.data = variables_page_text;
var varLoader_page_text:URLLoader = new URLLoader;
varLoader_page_text.dataFormat = URLLoaderDataFormat.VARIABLES;
varLoader_page_text.addEventListener(Event.COMPLETE, var_comp_page_text);
varLoader_page_text.load(varSend_page_text);
function var_comp_page_text(event:Event):void {
    MyImportedString = event.target.data.MyVariable;
php:
<?php
header('Content-Type: text/html; charset=utf-8');
$MyString = "some tekst &";
print "MyVariable=" . $MyString;
?>
   I've noticed that the special character '&' residing inside String, throws an error: #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.
My first thought was, it has something to do with html entities, but other entities (like <> or ") don't throw any error. Besides, the use of php functions like htmlentities(); or html_entity_decode(); doesn't make any difference in this case:
print "MyVariable=" . htmlentities($MyString);
or
print "MyVariable=" . html_entity_decode($MyString);
I've also noticed that characters like '%', '^', '+' don't show up at all;
What does it mean? Any ideas?
Reagards.

Thank You 'moccamaximum'.
Ok. So here is the solution (php function posted by 'moccamaximum' does the trick):
AS3:
var MyImportedString:String;
var variables_page_text:URLVariables = new URLVariables();
var varSend_page_text:URLRequest = new URLRequest("MyPHP.php");
varSend_page_text.method = URLRequestMethod.POST;
varSend_page_text.data = variables_page_text;
var varLoader_page_text:URLLoader = new URLLoader;
varLoader_page_text.dataFormat = URLLoaderDataFormat.VARIABLES;
varLoader_page_text.addEventListener(Event.COMPLETE, var_comp_page_text);
varLoader_page_text.load(varSend_page_text);
function var_comp_page_text(event:Event):void {
    MyImportedString = event.target.data.MyVariable;
     trace(MyImportedString);        // Output: some text &%^+
php:
<?php
header('Content-Type: text/html; charset=utf-8');
$MyString = "some text &%^+";
print "MyVariable=" . flash_encode($MyString);
function flash_encode($string){
     $string = rawurlencode(utf8_encode($string));
     $string = str_replace("%C2%96", "-", $string);
     $string = str_replace("%C2%91", "%27", $string);
     $string = str_replace("%C2%92", "%27", $string);
     $string = str_replace("%C2%82", "%27", $string);
     $string = str_replace("%C2%93", "%22", $string);
     $string = str_replace("%C2%94", "%22", $string);
     $string = str_replace("%C2%84", "%22", $string);
     $string = str_replace("%C2%8B", "%C2%AB", $string);
     $string = str_replace("%C2%9B", "%C2%BB", $string);
     return $string;

Comma problem with global string variable

Hi,
I'm fiighting with comma problem for global string variable. I've on page string for example "7nndqrr52vzyb,0" and by dynamic column link I'm assigning this string to global variable. Then I'm trying to display value of that global variable on another page but I see only string till comma, nothings more. I'm not sure what I'm doing wrong because when I'm trying to assign that value normally by computation process as a constant value is fine and see on another page correct string. I'll be really glad for help.
Thanks
Cheers,
Mariusz

When it tries to display the string, it sees the comma and wants to believe the string is terminated. You could escape the , in the string or replace it with a different character..

Problem with a String[] variable

Hi
I'm reading values from a table and I need to store them in a String[] variable.
This example shows I would do it without accesing to the database: String[] data = new String[] {"a","b","c"};
Now, I want to do the same thing but reading it from a database table. I do know how to read each value from the table, the problem is that I'm not sure on how to concatenate the values in the string[].
Thank you all in advance =)

Initialising strings with unicode characters

This works
System.out.println("Hello World");
but this will not compile
System.out.println("你好");
How do I get unicode characters into my Java source?
I am running Windows XP and editing my files using notepad.
If I save my source as ASCII it compiles, but I do not get the foreign characters.
If I save my file as utf-8 or unicode the source will not compile.

I have got it!
On Windows XP using notepad the java source file can be "saved as" Unicode.
The source can then be compiled using;
javac HelloWorld.java -encoding unicode
The code compiles and executes.
It is even possible to give variables names that are Chinese characters, which is really what you would expect to be able to do.

Insert Unicode Characters Into Oracle 8.1.5

Hello,
First off, here are the specs:
Oracle 8.1.5
JDK 1.2.1
Oracle8i 8.1.6.2.0 JDBC Drivers for use with JDK 1.2.x for Solaris
I'm running into a problem with insert Unicode characters into Oracle via the JDBC driver. As you can see above, I am using the Oracle 8.1.6.2.0 JDBC driver because it is the first driver with supports the JDK 1.2.x. So I think I should be okay.
I can retrieve data with special characters from Oracle by calling the getBytes() method from the ResultSet with all special characters being intact. I am using getBytes because calling getString() would throw the following exception: "java.sql.SQLException(): Fail to convert between UTF8 and UCS2: failUTF8Conv". However, with that value that I just retrieved, or any other data with special characters (unicode) in which I try to insert into Oracle does not get converted properly.
What appears to be happening is that data with special characters (unicode), are not being treated as a single double byte character, but rather two single byte characters. Thus, R|ckschlagventil becomes RC<ckschlagventil once it is inserted. (Hopefully, my example will be rendered properly).
According to all documentation that I have found, the JDBC driver should not have any problem with converting UCS2 Java Strings to Oracle's UTF8 character set.
I have set Oracle's NLS_NCHAR_CHARACTERSET to UTF8. I am also setting the environment variable NLS_LANG to AMERICAN_AMERICA.UTF8. Perhaps there is some other environment setting in which I am missing?
Any help would be appreciated,
Christian

Import has a lot of options, so it depends on what you want to do.
C:\> imp help=y
will show you all possible options. An example of full import :

Hey Sergiusz,
You were bang on target...
Though it took some time for me to resolve the issue...
to use SQLExecDirectW I need my query in SQLWCHAR *, which is stored in char * in my case...
So i converted the incoming query using MultibyteToWideChar Conversion with CodePage as CP_UTF8 and
then passed it on to SQLExecDirectW...
It solved my problem
Thanks,

What table column size is needed to accomodate Unicode characters

Hi guys,
I have encounter something which i dont understand and i hope gurus here will shed some light on me.
I am running a non-unicode database and i decided to port the data over to a unicode database.
So
1) i export the schema out --> data.dmp
2) then i create the unicode database + create a user
3) then i import the schema into the database
during the imp i can see that character conversion will take place.
During importing of data into the unicode database
I encounter some error
saying column size is too small
so i went to check the row that has the column value that is too large to fit in the table.
I realise it has some [][][][] data.. so i went to the live non-unicode database and find the row. Indeed it has some [][][][] rubbish data which i feel that someone has inserted other language then english into the database.
But regardless,
I went to modify the column size to a larger size, now the row can be accommodated. However the data is still [][][].
q1) why so ? since now my database is unicode, during the import, this column data [][][] should be converted to unicode already but i still have problem seeing what language it is.
q2) why at the non-unicode database, the [][][] data can fit into the table column size, but on unicode database, the same table column size need to be increase ?
q3) while doing more research on unicode, it was said that unicode character takes up 2 byte per character. Alot of my table data are exactly the same size of the table column size.
E.g Name VARCHAR2(5);
value - 'Peter'
Now if converting to unicode, characters will take 2byte instead of 1, isnt 'PETER' going to take up 10byte ( 2 byte per character ),
why is it that i can still accomodate the data into the table column ?
q4) now with unicode database up, i will be supporting different language characters around the world. How big should i set my column size to ? the longest a name can get ? or ?
Thanks guys!

/// does oracle automatically "look" at the each and individual characters in a word and determine how much byte it should take.
Characters usually originate from a keyboard, which has an associated keyboard layout and an associated character set encoding (a.k.a code page, a.k.a. encoding). This means, the keyboard driver knows that when a key with a letter "á" on it is pressed on a French keyboard, and the associated character set encoding is MS Code Page 1252 (Oracle name WE8MSWIN1252), then one byte with the value 225 is generated. If the associated character set encoding is UTF-16LE (standard internal Windows encoding), two bytes 225 and 0 are generated. When the generated bytes travel through APIs, they may undergo character set conversions from one encoding to another encoding. The conversion algorithms use translation tables to find out how to translate given byte sequence from one encoding to another encoding. In case of translation from WE8MSWIN1252 to AL32UTF8, Oracle will know that the byte sequence resulting from conversion of the code 225 should be 195 followed by 161. For a Chinese characters, for example when converting it from ZHS16GBK, Oracle knows the resulting sequence as well, and this sequence is usually 3 bytes.
This is how AL32UTF8 data gets into a database. Now, when Oracle processes a multibyte string, and needs to look at individual characters, for example to count them with LENGTH, or take a substring with SUBSTR, it uses information it has about the structure of the character set. Multibyte character sets are of two type: fixed-width and variable-width. Currently, Oracle supports only one fixed-width multibyte character set in the database: AL16UTF16, which is Oracle's name for Unicode UTF-16BE encoding. It supports this character set for NCHAR/NVARCHAR2/NCLOB data types only. This character set uses two bytes per each character code. To find the next code, 2 is simply added to the string pointer.
All other Oracle multibyte character sets are variable-width character sets, including AL32UTF8. In most cases, the length of each character code can be determined by looking at its first byte. In AL32UTF8, the number of 1-bits in the most significant positions in the first byte before the first 0-bit tells how many bytes a character has. 0 such bits means 1 byte (such codes are identical to 7-bit ASCII), 2 such bits mean two bytes, 3 bits mean 3 bytes, 4 bits mean four bytes. 1 bit (e.g. the bit sequence 10) starts each second, third or fourth byte of a code.
In other ASCII-based multibyte character sets, the number of bytes is usually determined by the value range of the first byte. Bytes below 128 means a one-byte code, bytes above 128 begin a two- or three-byte sequence, depending on the range.
There are also EBCDIC-based (mainframe) multibyte character sets, a.k.a shift-sensitive character sets, where a sequence of two-byte codes is introduced by inserting the SO character (code 14=0x0e) and ended by inserting the SI character (code 15=0x0f). There are also character sets, like ISO-2022-JP, which use more complicated byte sequences to define the length and meaning of byte sequences but Oracle supports them only in limited number of places.
/// e.g i have a word with 4 character. the 3rd character will be a chinese character..the rest are ascii character
/// will oracle use 4 byte per character regardless its ascii(english) or chinese
No.
/// or it will use 1 byte per english character then 3 byte for the chinese character ? e.g.total - 6 bytes taken
It will use 6 bytes.
Thnx,
Sergiusz

How to use Unicode characters with TestStand?

I'm trying to implement the use of Greek characters such as mu and omega for units. I enabled multi-byte support in the station options and attempted to paste some characters in. I was able to paste the mu character (μ) and import it from Excel with PropertyLoader. However, I have not had any luck with omega (Ω). I found the HTML codes for these characters on a web page (http://www.hclrss.demon.co.uk/unicode/) so I could use those codes for HTML reports, but that won't work for database logging, nor does it display the characters correctly for the operator interface. The operator interface is not a major problem, but the database must have the correct characters for customer reports. Anyone know how to do this? D
oes database logging support Unicode for stored procedure calls to Oracle?

Hello Mark -
At this time TestStand has no unicode support. The multi-byte support that we do offer is based on the Windows architecture that handles Asian language fonts. It really isn't meant to provide a bridge for unicode values in TestStand. Certainly, your Operator Interface environment will have its own support level for unicode, i.e. at this time neither LabWindows/CVI version 6.0 nor LabVIEW 6.1 officially support unicode characters. This is why you will see that the units defined in the TestStand enumerators are all text-based values.
I have run a quick test here, probably similar to what you were doing on your end, and I am uncertain if you will get the database behavior you want from TestStand. The database logging steps and API all use basic char sty
le strings to communicate to the driver. Even though you are reading in a good value from Excel, TestStand is interpreting the character as the nearest ASCII equivalent, i.e. "Ω" will be stored and sent to the database as "O". If you have a stored proceedure in Oracle that is calling on some TestStand variable or property string as an input, then it is doubtful you will get correct transmission of the values to the database. If your stored proceedure could call into a spreadsheet directly, you would probably have better luck.
