Tool is really great, but it would much better if it could support utf directory names.
Currently I can use only files /directories wirh latin letters. Russian or german names are beeing not opened by mp3gain.
Download the "Beta" version. It _kind of_ has UTF support. It will load and process the files just fine, but all non-Latin characters will appear as a "?" in the file list. That is due to a limitation in Visual Basic, and unfortunately would require a complete re-write of the GUI to fix :(
