Preserving Unicode Chinese?

Friends

Part of my job is to recommend programs for our members to use. Now, I have been looking into several free backup programs, and so far found only one that fulfill one of our very important requirements. That is, the program needs to keep the Chinese Unicode filenames intact in the backup files. Before I actually download and try Comodo Backup I want to know if this backup program will do that, or does it mess up the file names that are in simplified Chinese?

ps. The one I found so far is Cobian Backup. FYI.
