Fix encoding issues on Windows
Hydrogen fails to open songs with non-ASCII characters in file name or path on Windows.
When starting Hydrogen by double-clicking a song file or when using the -s or -p command line options the path of the particular file is handed to Hydrogen using the system's encoding. If the encoding is e.g. windows-2151 and the file name or path contains e.g. Cyrillic or Japanese characters, all non-Latin-1 characters are lost and Hydrogen has no way to determine the correct path of the song and won't be able to open it.
You have to enforce UTF-8 encoding on your system. (Which is most probably a very good idea anyway since you are using non-ASCII filesnames).
