I have a problem in eclipse, i imported a project , maybe i changed the encoding to UTF-8 then i reset it back to default; but in the whole code where there is special characters like accents , they turned into unreadable symbols (as the screenshot show). is there any ways to reformat the code and get back the original code. Know that when i write myself accented letters it's shown as normal without problems

I wrote a program that reads from a file has Arabic text encoded with ANSI.
I made a runnable jar of that program.
It run perfectly on my Laptop, however, when I run it on another laptop the Arabic characters turn into a messy symbols.
So what to do?
Make sure your end system is having the fonts required to display those letters if not bundle it with your application.
Check whether you are reading the file content UTF-8 (Or appropriate encoding format).
I am building an app that takes information from java and builds an excel spreadsheet. Some of the information contains international characters. I am having an issue when Russian characters, for example, are rendered correctly in Java, but when I send those characters to Excel, they are not rendered properly. I initially thought the issue was an encoding problem, but I am now thinking that the problem is simply not have the Russian language pack loaded on my Windows 7 machine.
I need to know if there is a way for a Java application to "force" Excel to show international characters.
Thanks
Check the file encoding you're using is characters don't show up. Java defaults to platform native encoding (Win-1252 for Windows) instead of UTF-8. You can explicitly set the writers to use UTF-8 or Cyrillic encoding.
In my application I need to assign Chinese characters to a string to be diplayed on the screen. If I simply do this...
String chinese = "我是你的朋友";
It says it doesn't support it and I have to save everything in UTF-8 format. Will this mess my project up? I'm not sure what the best way to do this is.
Thank you
If you save all the files in UTF-8 format and also tell the Java compiler to use UTF-8 as the file encoding (refer to the documentation of your IDE or build tool), then it will work just fine.
I have a Java application that is generating JasperReports. It will create as many as three JasperPrints from a single report: one prints on the printer, one is serialized and saved to the database, and the third is exported to PDF using Jasper's built-in export capability.
The problem is that when exporting to PDF, characters containing 8 or more bits (i.e. not 7-bit ASCII) are showing up as empty squares, meaning Acrobat Reader is not able to display that character. The print version is correct, and loading the database version and printing it shows up correctly. If I change the PDF exported version to a different format, e.g. XML, the character shows up fine in a web browser.
Based on the evidence, I believe the issue is something specific to font handling in PDFs, but I am not sure what.
The font used is Lucida Sans Typewriter, a Unicode monospaced font. The Windows "font" directory is listed in the Java classpath: without this step, PDF exporting fails miserably with zero text at all, so I know it is finding the font.
The specific characters not displayed are accented characters used in Spanish text: á, é, í, ó, and ú. I haven't checked ñ but I am guessing that won't work too.
Any ideas what the problem is, areas of the system to check, or maybe parameters I need to send to the export process?
The PDF encoding used for exporting was UTF-8, and apparently the font didn't support that properly. When I changed it to ISO-8859-1, every character showed up correctly in the PDF output.
In iReport, try setting the Pdf Embedded property of your TextFields to true.
I'm using Jasper Report 6, My team has spend a few days to display Khmer Unicode. I have found solution finally, and everything work as expected.

after you exported, upload your jar file to lib folder and restart your jasper server.
I have a Java project that connects to a C# program that prints Turkish words. Printing Turkish characters in C# using console is not causing any problems. However, the main issue is that when this C# program is called from Java, the Turkish characters are printed weirdly.
What I would like to do is to get the output printed on console and reprint it using Java GUI without having any problems with Turkish characters.
I really appreciate any kind of help.
Many thanks in advance
The issue is likely to be that the C# application is encoding its character data in one encoding while the Java application is decoding the data as another. Assuming Windows, it is possibly an ANSI/OEM mismatch.
You need to identify the encoding the C# application is emitting. In the Java application, read each byte and check its hex value. Check to see if the bytes are Windows-1254, OEM-857 or whatever and then decode them appropriately using a reader with the appropriate encoding.
