lots of fsCharset, utf8/ascii converting clean-up and robustness stuff
Also, if fsCharsetToUtf8 can't convert to valid UTF-8, then don't add it to the db, this way clients don't have to worry about weirdness and it will force ppl to convert it. git-svn-id: https://svn.musicpd.org/mpd/trunk@711 09075e82-0dd4-0310-85a5-a0d7c8717e4f
