names of files and folders
 

BSplayer can't open (status stays on "closed") any files or files in folders that have names containing non-standard characters.
For example russian, chinese, japanese names, when not using those languages as main language (the "use this language for programs that don't support Unicode" option in regional settings in control panel).
Oh no... again, no Unicode support T_T

don`t worry, winamp also has got problems with polfonts

Unicode support will be added in one of next build, a lot has to be changed.
