Unicode file names are supported, so it is possible to rename without problems files that have names containing characters from Japanese, Chinese, Arab, etc. This may seem common nowadays, but back then when it was added (2003) it was a big plus.

Tested successfully under various Windows versions, from 98 (possibly with a few updated system files) and NT4 (SP4 required) up to current ones (Windows 10/11 included).

Known bugs and limits

Unicode is supported only on NT systems (Windows NT4, 2000, XP, Vista, 7, 8, 10 and equivalent server versions)
However, the translation of user interface works only if the language defined in Windows regional settings uses the same character set as the language selected in the program
Since version 2.04 the program does not start on Windows 95, it seems to be caused by a missing function on this system
In the "Use date & time" action, if you use a long date format (with day or month in letters, like "December" in English), it will fail for days or months that have special characters in their name (like "Décembre" in French); this bug will be corrected some day
