Anyway. I think Synchronize dirs has a bug in its handling of unicode in filenames. It's reproduced in a rather obscure way however, and I'm not sure TC can do anything about it, but think it's worth the try

First, create some directory with a file in it, named using some CJK characters, I pressed random keys and got 嘎提毒.txt. Then navigate to a shared directory on some other computer. (Computers running WinXP work correctly, but for example a Samba server reproduces the bug. Perhaps it has something to do with OS unicode handling?)
Copy the new file to a testing dir on this share, and proceed to compare the (identical) directories. On my computer, this results in the following:
(Can't post images yet, spam protection? It shows the Sync tool, offering to copy one file in each direction, with all file data exactly identical.)
Trying to synchronize the directories will result in TC asking me if I want to overwrite the files, and when it's done, recompare the directories and again show a difference.
Using regular XP shares or just two directories on the same PC produces no problems (ie no differences), but since the names display the same in TC I was hoping a fix would be possible.
I'm using Windows XP Home edition SP2 with TC 7.02a.
