Doesn't Work with Asian Characters

For example, Chinese characters in folder names are represented as question marks, and Duplicate Cleaner does not accept these kinds of folders.

Error:
---------------------------
Duplicate Cleaner
---------------------------
---> c:\Users\Computer Owner\Desktop\??????

This search path is invalid.
---------------------------
OK

You are right - Duplicate Cleaner 1.4 doesn't support Unicode file/folder names - a limitation of the underlying libraries.
However Duplicate Cleaner 2.0 works perfectly with asian/unicode characters - unfortunately this isn't ready for release yet!
