How do I use the old FoF-1.2.X search?

Right now if you press a key it uses the RF-mod jump keys to go to the first song/folder of that letter. If you want to use the FoF-1.2.X search filter press '/' first

Why don't my non ascii characters show up correctly anymore?

Many people experienced crashes in FoF when their song.ini's or folder names contained non ascii characters. Python does not deal with those well and makes it fairly difficult to use unicode.

In your fretsonfire.ini file locate the [game] section and insert a variable that says

encoding = utf-8
encoding = Latin
encoding = ascii
