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.

Filenames with unicode characters

Hello, I have a question regarding filenames with unicode characters on an arabic windows xp.
I have a string, which the user entered and want to create a file with this string as filename. So my question:
Which unicode characters are allowed in a filename? I know, that on a german windows " / \ * ? < > : * are not allowed from the ASCII set, but which unicode chars are allowed? Is this language dependend on windows? Maybe there exists a method, which checks a string for this allowed characters.
Thanks for your help

AFAIK the illegal characters are always the same (you listed them already) and as long as the filesystem supports it (read: you use NTFS and not FAT) you may use any other unicode character.
You might have troubles displaying those characters 'though if you don't happen to have the correct fonts installed, but that would only be a cosmetic issue.

Performance of JEditorPane with unicode characters

Hi,
I'm using a JEditorPane to edit rather large (> 15000 words) but simple HTML files. Everyting is fine until I add even a single unicode character to the text with a character code higher than 255, like a Greek omega (\u03A9). With the unicode character the control starts to take an incredibly long time to redraw (sometimes minutes) when you resize it, for instance. The strangest thing is that removing the character again does not restore performance. Can anyone explain why this is happening?
import javax.swing.*;
import javax.swing.text.html.HTMLEditorKit;
public class EditorPaneTest {
public static void main(String[] args) {
StringBuffer html = new StringBuffer();
html.append("<html><body>");
// Uncomment next line, run and resize frame to see problem
// html.append("<p>\u03A9</p>");
for (int i = 0; i < 2000; i++) {
html.append("<p>Testing, testing, testing...</p>");
html.append("</body></html>");
JFrame jFrame = new JFrame("Test");
jFrame.setSize(300, 300);
JEditorPane jEditorPane = new JEditorPane();
jEditorPane.setEditorKit(new HTMLEditorKit());
jFrame.add(new JScrollPane(jEditorPane));
jFrame.setDefaultCloseOperation(JInternalFrame.EXIT_ON_CLOSE);
jFrame.setVisible(true);
jEditorPane.setText(html.toString());
}Any help would be much appreciated.
Thanks,
Rasmus

In the meantime, I had to solve my problem one way or another, and the only thing that came up to my mind was to use JavaMail API.
It is not quite what I was hoping for, because it doesn't provide opening of default e-mail client on local machine, but at least it can send e-mail with Unicode characters in the subjects line, recipient addresses, etc.
Make a new message using JavaMail and then set it's properties in a fairly simple manner, like this:
message.setSubject( MimeUtility.encodeText("+ ... some Unicode text with Cyrillic symbols ... +", "UTF-8", "B") );I'd still like to see if there are any suggestions on how to do the similar thing with java.awt.Desktop.

CRVS2010 Beta - Cannot export report to PDF with unicode characters

My report has some unicode data (Chinese), it can be previewed properly in the windows form report viewer. However, if I export the report document to PDF file, the unicode characters in exported file are all displayed as a square.
In the version of Crystal Report 2008 R2, it can export the Chinese characters to PDF when I select a Chinese font in report. But VS2010 beta cannot export the Chinese characters even a Chinese font is selected.

Barry, what is the specific font you are using?
The below is a reformatted response from Program Management:
Using non-Chinese font with Unicode characters (Chinese) the issue is reproducible when using Arial font in Unicode characters field. After changing the Unicode character to Simsun (A Chinese font named 宋体 in report), the problem is solved in Cortez and CR both.

Does photoshop cs5 sdk support file names with unicode characters?

Hi,
For the export module, does the windows sdk have support for filenames with unicode characters?
The ExportRecord struct in PIExport.h has an attribute filename declared as char array.
So I have a doubt whether filenames with unicode characters will be supported for export module.
Thanks in advance,
Senthil.

SPPlatformFileSpecificationW is not available in ReadImageDocumentDesc.
It has SPPlatformFileSpecification_t which is coming as null for export module.
I am using phostoshop cs5 sdk for windows.
Thanks,
Senthil.

Convert document into string with unicode

I want to convert my document into string with all <,>,& to be converted into <, >, and &. When I am doing transformation, I am getting <,> etc.
Can anybody suggest me how to do that.
regards,
Ranjan

I don't know of any way to tell the parser to convert is for you, you'll have to replace the characters yourself after you got the string from the parser.

QRcode printing with unicode characters

Hi,
We're trying to print out QRcode in smartforms by referencing below link with output device ZBWIPP and device type ZBWIPPQR.
http://www.rjruss.info/2010/09/how-to-printpdf-qr-codes-in-standard.html
Meanwhile, we need to print out trad. Chinese in same smartform.
Seems that QRcode and trad. Chinese are in different character set.
Would there be any device type which supports QRcode and unicode ?
or any revision requires for ZBWIPPQR device type?
Please help.
Thank you.

Hello Nieves,
Just came aware of your question and see its been a while so you may have moved on.
However I created the post you refer to.
Also I posted the following SCN blog post that covers using a Japanese Device type to allow Kanji with the QRcode.
The SAP note referenced in the blog also has Chinese device types so could be adapted. The device types do come with some limitations so may not be suitable in all cases.
If you still have the requirement have a read of my SCN blog and happy to help further if required.
Cheers

Parsing strings with Unicode values 16 bits

How can I get the Unicode value for a character in a String when the value is greater than 16 bits?
I need to extract a supplemental plane Unicode value from a string. However, String.charCodeAt(index) truncates the Unicode value to 16 bits, returning what should be 0x02F91A as 0xF91A. I see discussions that show that earlier versions of Flex stores such char codes as the two code points of a surrogate pair, but in Flex 4, the string length is just 1 when I put only this character in the string.

Does it work in JavaScript? Could send it over via externalInterface.

[SQL 2012] split string with forbidden characters

Hi all,
I have an issue with a query
I would like to find an equivalent of pivot function, but with a column that contains forbidden characters (like []&) and using delimiter (,), and when number of value on column could be different :
colA              colB                   colC
toto              titi                     [valeur].[membre].&[test1],[valeur].[membre].&[test2],[valeur].[membre].&[test3]
tata              tutu                   [valeur].[membre].&[test4],[valeur].[membre].&[test5]
fifi                fafa                    [valeur].[membre].&[test6]
fofo              fufu                    [valeur].[membre].&[test7],[valeur].[membre].&[test7],[valeur].[membre].&[test9]

Splitting a string with special characters

Alrights, lets say I had a string, which will be defined as "1 + 2 + x". I want to split the string into a string array with " + " as my delimeter. How would I do so?
String blah = "1 + 2 + x";
String blahTwo[] = blah.split(" + ");
System.out.println(blahTwo[0]);this would out put "1 + 2 + x" instead of "1".

The compiler gives an error if the delimeter is called as "+" for the
split method.Javac doesn't care but the RE compiler does. If you want to split a
string around the '+' chacacter use "\\+", i.e. one backslash to keep
Javac silent and the other one to keep the RE from whining.
kind regards,
Jos

How to set a variable to a string with special characters?

I want to set a variable to
<cfset inputstring = "<img src="../../../server/win/form/stamp/string_1" />"/>
but i keep getting error:
Invalid CFML construct found on line 184 at column 32.
ColdFusion was looking at the following text:
I have try it different ways , what i'm i doing wrong?

You have to either escape the inner quotes or mix single and double quotes. Try:
<cfset inputstring = "<img src=""../../../server/win/form/stamp/string_1"" />"/>
or
<cfset inputstring = '<img src="../../../server/win/form/stamp/string_1" />'/>
Oh, and the trailing forward slashes aren't necessary in the <cfset> tag.

Problems on selecting views with french characters into column names

Hi All,
I have views with column names such as "Détermination Planimétriq" or "Année de construction:*";
I can get in my c# function this columns names from ALL_VIEWS dictionary table, but if I try to make a selectionby use of an OracleCommand, Oracle returns an "Invalid identifier" error:
SELECT "Détermination Planimétriq" FROM mytable;
System.Data.OracleClient.OracleException (0x80131938): ORA-00904: "Determination Planimetriq": invalid identifier at System.Data.OracleClient.OracleConnection.CheckError(OciErrorHandle errorHandle, Int32 rc) at ...
Any suggestion?...

Be wary of using character codes outside the Western European "simple" alphanumeric [A-Z0-9] for object names, i.e. columns, table names, function and procedure names, and so on.
First reason, there is a 30 character limit for most object names, and characters that have to be spelled out with unicode characters take more space, i.e.:
select dump( 'Détermination Planimétriq' ) from dual;
DUMP('D?TERMINATIONPLANIM?TRIQ')
Typ=96 Len=29: 68,239,[ ... ]Although the varchar string for that column name looks like 25 characters, it needs room for 29 to store the e<acute> character. And could also depend on the client settings. Using case sensitive names is not a best practice, its better to avoid specifying objects with the double quotes.

Search and replace for Unicode characters

Hello,
I have a function which searches and replaces characters on file. It works with ASCI sharacters, but not when the strings which needs to be replaced contains Unicode ('á', 'ā') etc. The source file is codding
utf8 .
$file = "file.txt"
$SearchReplace = @($file)
#Process files by performing a search and replace
foreach ($file in $SearchReplace)
#Select-Object -Skip 1 |
(Get-Content $file) |
Foreach-object { $_ -replace 'unicode_string' , ';' } |
out-file -encoding Unicode $file
How to get working the search (and replace) function with Unicode characters?
Thanks!

No. it does not. I have verified that script does not recognize the diacritic
('á',
'ā') characters when at all the operations with the files I have specified encoding utf-8/Unicode.

Getting PDF filename with unicode chars

Hello,
I'm trying to write a plugin that gets the file path of the current active document. The code looks like this:
AVDoc avDoc = AVAppGetActiveDoc();
PDDoc pdDoc = AVDocGetPDDoc(avDoc);
ASFile file = PDDocGetFile (pdDoc);
ASPathName filePath = ASFileAcquirePathName (file);
This works fine for most documents, but for documents with unicode characters in the name each unicode character is replaced with '.' in filePath. For example, if the document is "测试中文关键词搜索!@#$%^&().pdf", then filePath becomes ".........!@#$%^&().pdf". Am I missing something required to get unicode filenames?
Thanks.

You were right, the plugin was getting a char* from ASFileSysDisplayStringFromPath. I removed that and added this which seems to have fixed my problem:
ASText pathText = ASTextNew();
ASFileSysDisplayASTextFromPath(ASGetDefaultFileSys(), filePath, pathText);
wchar_t *pathString = (wchar_t*)ASTextGetUnicode(pathText);
Thank you!
