Java source file encoding with Chinese character

I import a Java project from Windows platform to Ubuntu.

My Ubuntu is 10.10, Gnome environment: My LANGUAGE is set to en_US:en

My terminal's character encoding is: Unicode (UTF-8)

My IDE is eclipse and text file encoding is: GBK.

In source file, there are some Chinese constant character.

The project build successful on Windows with ant,

but on Ubuntu, I get compile error:

illegal character: \65533  

I don't want to use \uxxxx format as the file is already there,

And I've tried the -encoding option for javac, but still can't compile开发者_高级运维.

I think the problem lies not with Ubuntu, Ubuntu's console, Javac or Eclipse but with the way you transfer the file from windows to Ubuntu. You have to store it as utf-8 before you copy it to Ubuntu otherwise the codepoint-information that is set in your Windows your locale is already lost.

Did you specify the encoding option of the <javac> task in your build.xml?

It should look like this:

<javac encoding="GBK" ...>

If you haven't specified it, then on Windows it will use the platform default encoding (which is GBK in your setup) and on Linux it will use the platform default encoding (which is UTF-8 in your setup).

Since you want the build to work on both platforms (preferably without changing the configuration of either platform), you need to specify the encoding when you compile.

You need to convert you source codes from you windows codepage to UTF-8. Use iconv for this.
