Eclipse c/c++ have odd characters when text file encoded with UTF-16

[coder1998]

I am using Eclipse for c++ project. I have some polish characters need to be in the code. When I switched the encoding to UTF-16, the editor shows odd charactrs. Not sure why this happened. If I swtich to UTF-8, it works fine. Maybe I should just stick to UTF-8. Anyone have luck using UTF-16 text encoding?

C++ sources should only contain ASCII. There's no telling what will happen if you try to compile that.
