2-byte character's problem
 

If a 2-byte character (Japanese) is contained in a file name or full path, even if it close file or under file reproduction or after reproduction, and it double-clicks a file, reproduction will not start.
With the Japanese bulletin board, it reappears in all environments.
There are also those who create the patch of bug fix.
If it opens in a double click, a file name will be flown as a window message. The portion which opens a file is ordinarily treated by ASCII to logging of the file name being Unicode. If a multi-byte character like Japanese is contained in a path, mismatching will occur.
