Sure I can, but please do note that this is to run Java via a Command Prompt using MSDOS Windows:
1. Each time you open up a DOS Window (by clicking on Start logo, then All Programs, then Accessories, then Command Prompt)
2. Set the Window environment to Unicode by typing at the prompt:
chcp 65001 (and then press the Enter/Return button)
3. If you have written a Java program and lets say it's called TestUnicode.java, then type the following to compile the code:
javac TestUnicode.java (and then press the Enter/Return)
4. Then finally, to run the program called TestUnicode that has Unicode characters that are stored in Strings and Collections, then type the following:
java -Dfile.encoding=UFT8 TestUnicode
5. Assuming that your program displays the Unicode characters, then you will see at the DOS Window your Unicode characters being displayed correctly (hopefully).
I hope the above helps.
