Problem in Spl Characters handling

Hi Friends,
We are developing a applicatio using J2EE Tech.,
Problem which we face now is with spl character.
There is text box in our application, If are entering the data(even spl char) it is storing in the database properly and diaplays it correctly.
But when we copy paste the content(eg., "," and "'") from MS Word to this text box it is giving problem. ie., in Oracle database it is stored as spl characters�.pls try to give a solution.
Thanks in advance,
Balamurali

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.

Problems with special characters like "u00F6" "u00E4" "u00FC"

Hi,
we currently face some major problems with special characters like "ö" "ä" "ü". First I thought it is a SP02 specific problem but it still doesn't work with SP03.
When I start an import the import manager shows correct converted value. "ö"s "ä"s "ü"s are displayed correctly. But after I've done the import I look into the Data manager and I see instead of these characters charcaters like "̈". (note: the character should show a little square box - but the forum cannot desplay it)
How can I solve this problem?
Regards
Nico

Hi Nico
Just try it out the following steps, hope it solves ur issue.
To set one or more values back to their original values:
1. In the Import Manager Source Values grid, select the values that you want to set back to their original values.
2. Right-click on one of the values and choose Set to Original Value from the context menu, or choose Values > Apply Value Conversion Filter > Set to Original Value from the main menu.
3. MDME sets each value back to its original value, which appears in black in the Source Values grid.
NOTE : You can use the Set to Original Value filter only at the value-level and not at the field level.
thanks

SMARTFORM problems with special characters

Hi everybody,
only to know if somebody knows how to fix a problem printing special characters in a smartform, instead of some characters the smartform display (Print preview) and prints interrogative symbols "?".
If someone knows about this problem, it will be helpfully for me,
thanks and have a good day

HI
To display Special characters in Smartforms ...
goto text editor of the perticular text node.
in the text editor, Click INSERT - Characters - Displayable Characters.
a new window will open showing all characters...if ur required character is not
present, click on non-dispalyble character button , it displays all the characters
and their respective numbers...select ur required character .
Check it, if it is helpfull reward points..
Thanks

Problems with special characters with XML/PDF printing

Hi,
Our setup:
Apex Listener 2.0.5
Oracle DB 11G
Weblogic
Apex 4.2.2
Various recent major browsers
We used this blog post so we could do some PDF printing with APEX Listener:
http://marcsewtz.blogspot.be/2013/04/pdf-printing-with-oracle-application.html
The problem is special characters. For example the "&" sign comes out as "%26amp;" when we export an XML.
Could anyone provide some insights of what we can do to fix this?
Regards,
Joni

Problems with special characters in InputStream or XPath

Hello everyone,
I am having problems with special characters such as ", ', - and so on, everything becomes ? (questionmark). (Not with special nordic characthers (å,æ,ø) though.)
The encoding of the XML is UTF-8, and the server that holds the webservice is setting encoding to UTF-8 also, so no conflict there.
What I have done is something like this:
{code}
String url = "http://www.formula1.com/rss/news/latest.rss"; // This is not the feed I use, it is a custom XML document
InputSource is = new InputSource(url);
DocumentBuilderFactory fct = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = fct.newDocumentBuilder();
Document doc = builder.parse(is);
Element rootElement = doc.getDocumentElement();
XPathFactory factory = XPathFactory.newInstance();
XPath xPath = factory.newXPath();
out.print(xPath.evaluate("/rss/channel/title", rootElement)); // The xml is not a RSS feed, this is just an example.
{code}
Please let me know what I am doing wrong, or give me a hint of how to solve this in another way.
Best regards,
G.Hansen

Hello, thanks for you reply. I had to rewrite your code a little, and I think that your code would not really compile, if you tried yourself :-)
I ended up with something like this:
our environment is running in 1.4 mode, so I could not use the for-each loop :-(
public String printEntities(String s) {
 char[] sArray = s.toCharArray();
 StringBuffer sb = new StringBuffer();
 for (int i = 0; i < sArray.length; i++) {
 if (sArray[i] > 256)
 sb.append("&#x" + Integer.toHexString(sArray) + ";");
 } else
 sb.append(sArray[i]);
 return sb.toString();

How to send Oracle rowid to servlet? | Problem with national characters.

There is same possibility how to send rowid to servlet?
I have now definition like this:
<af:image source="/imageservlet?Par1=#{bindings.Col1.inputValue}"/>
But If column contents national characters, servlet methods obtained changed these characters.
My idea is to use not primary key for row, but use oracle rowid. It is simply possible?
Use something like this:
<af:image source="/imageservlet?Rowid=#{bindings.Rowid}"/
Or Do you have ideas how to solve problem with national characters ?
Thanks
FiL

Hi,
Although your workaround works.
I think this is a simple encoding problem.
I simply need to make sure all parameters and pages are encoded with a char set which contains the national characters you mentioned.
This is a bit dependent on the exact technology your using, but most can be done via the web.xml:
<jsp-config>
 <jsp-property-group>
 <url-pattern>*.jsp</url-pattern>
 <page-encoding>UTF-8</page-encoding>
 </jsp-property-group>
</jsp-config> This forces all JSP pages to be encoded in UTF-8
Adding the following parameter sometimes helps as well, although I think this one is a bit dated:
You said your using a servlet so your servlet needs a similar block for its pattern
<context-param>
 <param-name>PARAMETER_ENCODING</param-name>
 <param-value>UTF-8</param-value>
</context-param>If you want to be 100% sure the encoding is set right make sure thepages contain:
<%@ page contentType="text/html;charset=utf-8"%>Or depending on your view technology the syntax can be a bit different

Problem with national characters on windows client

Hello there,
I'am having problem with national characters on windows client.
All national data stored in NVARCHAR2 colums, applications (.net) works fine,
but in sqlplus:
select city from test_table;
- everything ok, sqlplus shows national characters
select dump(N'<national symbols>') from dual
- returns
Typ=96 Len=12: 0,191,0,191,0,191,0,191,0,191,0,191
select * from test_table where city = N'<national symbols> '
- always returns nothing
As i understand the problem in
sql query text (and national literals) convertion
to servers "WE8ISO8859P1" encoding, Is it possible
to solve the issue?
Thanks in advance
PS.
Console in right mode (chcp=1251)
sqlplus shows russian messages well
Server (oracle 9 on solaris):
select * from nls_database_parameters
NLS_NCHAR_CHARACTERSET AL16UTF16
NLS_SAVED_NCHAR_CS WE8ISO8859P1
NLS_LANGUAGE AMERICAN
NLS_TERRITORY AMERICA

NLS_SORT BINARY

NLS_TIME_TZ_FORMAT HH.MI.SSXFF AM TZH:TZM

NLS_RDBMS_VERSION 9.2.0.6.0
Client (windows server 2003, oracle client 10):
NLS_LANG = RUSSIAN_CIS.CL8MSWIN1251

N'<national symbols>', being part of an SQL statement, will be converted to the database character set (WE8ISO8859P1) before being parsed. Only if the client and the database are both 10.2 or higher, the client can encode the literal appropriately so that it survives this conversion.
In earlier versions, you can do the encoding yourself. Instead of the N'<national symbols>' literal use the UNISTR function: UNISTR('\xxxx\yyyy\zzzz'), where U+xxxx, U+yyyy, U+zzzz are Unicode code points of your national characters.

Problem viewing Japanese characters in Excel sent via Email attachment

Hi All
I am using FM '''SO_DOCUMENT_SEND_API1'' to send out an e-mail attachment (Excel file). I am able to receive the Excel file successfully. However I am not able to display the Japanese characters properly in my Excel file.
I tried to display some Japanese characters in my e-mail contents and I have no problem viewing these characters in my e-mail (I am using MS Outlook 2003). These statements becomes something illegible when I transfer it over to Excel as an attachment. In my Internal Table, these characters are displayed correctly as well.
Anyone has any advice to solve this issue?
Thanks for your replies.

Hi Divya,
refer to the link below:
http://www.sapdevelopment.co.uk/reporting/email/attach_xls.htm
The code in this demonstrates how to send an email to an external email addresswhere the data is stored within a .xls attachment.
Hope this helps.
Reward if helpful.

WE + CE cause problem with accented characters

While creating a CFF font which contains the WE as well as the CE character set, it causes problems with most of Adobe programs (Photoshop 7, Illustrator 10, Photoshop Elements 2.0) under Mac OS X. Problem: the accented characters get replaced by Helvetica (Photoshop) or Myriad (Illustrator). Only InDesign treats it right.
I tested under Mac OS X 10.2 as well as 10.3; no difference. I tested on 'old machines', but fresh machines as well (machines which didn't have the fonts installed before); no difference. All the same problem.
Deleting the CE characters solves the problem, but yeah, I want to create a CFF font which contains both character sets.
Generating the font in FontLab or FDK doesn't make any difference.
So, what's the solution? Sounds like a mystery.
Bas

Two comments:
OpenType/CFF fonts should work to some degree on versions of Mac OS from 8.x on. "Some degree" means that pre-Mac OSX, you need ATM for them to work, and you only get the Roman char set. On Mac OSX, Unicode savvy apps will give you access to the entire charset, but at the moment only Adobe apps support any OpenType features.
About your problem with CE charset: this is a known problem, and is still a mystery. Adam Twardoch has reported the same problem and has supplied some test fonts. I have spent over a day looking over the fonts, and looking into old code, and can't find any problem in the font data. Investigating further is likely to be a several day effort, and will happen, but not soon.

Application Hudba (Music) problem with Czech characters

Hello,

Problem with accentuated characters in XLIFF file (no problem anymore)

Sorry, the following turned out to be a non-problem. XLIFF editor understands accentuated characters in the translation file very well :o)
I am trying to translate an APEX v 2.2 application from french to german.
Generated xlf file header reads:
<file original="f101_102_fr-ch_de.xlf" source-language="fr-ch" target-language="de" datatype="html">
All french diacritical characters in the file are replaced by something like Ã©. Something similar happens when one exports CSV file to Excel with Automatic CSV Encoding set to "No".
Application main language can be swiss french (fr-ch) or french french (fr), with the same result.
Application Language Derived From is "Use application primary language"
Automatic CSV Encoding is set to "Yes".
Is there a possibility to export non-english characters correctly?
Thank you.

Well... In a way, it was my fault. I have created xliff file and looked at its contents using CodeWright text editor. Using CW's regular expressions and macros, one could process translation fairly easily.
However, in this file foreign characters are scrambled (=> my post).
Then, I decided to install and try XLIFF editor. The one recomended by SUN handled all diacritical characters nicely.
So, as long as I don't try to proceed to direct translation of the xlf file, but through XLIFFF editor, I don't have to worry about french and german accents. At least, I hope so (I still have to import the german translation to be sure).

Problem with Special characters(Russian) using DynamicConfiguration

Hi,
I have a mail-RFC scenario where I am using adapter-specific message attributes and DynamicConfiguration to retrieve mail subject.It works fine.
We have a problem when the subject contains Russian special characters.In this case,whole mail subject gets converted into an irrelevant string.
Can anyone please suggest how to handle special characters in DynamicConfiguration using ASMA .
Thanks a lot for your help in advance.
Regards,
Shweta

Your UDF could be something like this:
String output = null;
String strs[] = input.split("\\?");
String charset = strs[1];
String encoding = null;
switch (strs[2].charAt(0)) {
     case 'Q' :
          encoding = "quoted-printable";
          break;
     case 'B' :
          encoding = "base64";
          break;
     default :
          break;
String subject = strs[3];
try {
     InputStream is = new ByteArrayInputStream(subject.getBytes());
     InputStream dis = MimeUtility.decode(is, encoding);
     ByteArrayOutputStream out = new ByteArrayOutputStream();
     byte[] b = new byte[4096];
     for (int n;(n = dis.read(b)) != -1;) {
          out.write(b, 0, n);
     output = out.toString(charset);
} catch (Exception e) {
     //implement catch...
return output;
where input is the input string.
For test purposes, use
String input = "=?KOI8-R?B?Rnc6IDEwMjEwMTMwLzA1MTEwNi/wMDE3NDkzLw==?=";
or
String input = "=?utf-8?Q?Auftragsbest=C3=A4tigung?=";

Problems with special characters when exporting to LDAP

Hi,
Im using standard report RPLDAP_EXTRACT to export data to LDAP. The problem is that the special characters (in this case polish letters) do not save correctly (we get for instance '?' instead of normal letter)
I tried switching the configuration of the RFC destination (used: 'found communication Code Page option') but I get a message: "Your selection is restricted" and cannot make any changes.
Can anyone please help in this matter?
Regards,
Hubert

1) Your database should be able to handle and properly store all the supported charactersets needed. With UTF you are in the clear regarding storing all that kind off idfferent characters
See http://www.oracle.com/technology/tech/globalization/htdocs/nls_lang%20faq.htm
2) The recieving party (the cleint software) hopefully has a character set that supports all the characters that are offered by the database and can encode them. If not then you get toe upside down question markt or dark squares or something alike. If the client software is a browser, for instance windows internet explorer, then most encoding settings are buildin and you only have to switch. Sometimes you will have to add extra language support on Windows Internet Explorer. This behaviour is also the same on thick clients. Oracle by default sets these parameters in the registry, but on windows the can be overrulled on several levels like on system level, user level (start --> settings -- control panel --> system --> advanced tab --> environment settings) and or during execution via a app. configuration file or an export of the system variable on the command prompt... A unified business approach for how to handle this is needed otherwise you will have too look for these kinds off issues always all over the place (on windows and/or linux etc).
Have a look at Mark's example of how things work regarding UTF and the like on the FAQ URL on this forum and the URL as show above. If completely lost, you will have to read up on it in the Oracel globalization / NLS manuals and see what is appropriate / can be done in your environment.

Problem with SAX characters method

Well I already used SAX on couple occasions, and there was no problems. But this time I have weird situation. characters method from handler class (SAX parser) does not handle XML element at once, but in two passes. For example:
<some>this is some text</some>is handled by calling characters method TWICE (e.g. 'this is' and 'some text'). Is this normal behavior, or I do not form XML file properly? If it is normal, can anyone tell me how to detect this behavior?
Every help is appreciated. Cheers!
