英文原文

If you use the UNIX/Linux platform, you can start the IDE with the UTF-8 locale. Most modern UNIX/Linux platforms support UTF-8 locales. For example, if you use Japanese, 

% export LANG=ja_JP.UTF-8
% netbeans
How to set the encoding on Windows?
There is no way in Windows to change the locale at IDE startup. This means for example, that the IDE always uses Shift_JIS on Japanese Windows. When you want to use UTF-8 encoding in Java sources file, you need to change the encoding of the source editor, and add a compiler option. Please follow the steps below. 

Open Option dialog by Tools > Option 
Switch to Advanced Options 
Click the Java Source node of the Editor Editing category 
Find the "Default Encoding" field and enter "UTF-8" into the field 
This is the setting just for the Editor. Now you need to set compiler options: 

Open the project's Property dialog 
Find the "Aditional Compiler Option" field in the "Build" category 
Enter "-encoding utf-8" into the field 
How to change the encoding for other text files, e.g. .txt, .js files?
Currently, there is no recommended solution. Some people use the "-J-Dfile.encoding=UTF-8" switch as IDE startup option, but it's not a perfect solution.
