More about Special Characters

[MarmiteSandwich]

I am creating playlists from iTunes, using a utility which claims to know about Unicode and has an option to cover this (java -jar itunesexport.jar -useM3U8Ext). I have many artists or albums which contain these characters, which then find their way into folder and file names, obviously. I have been using Minimserver under Windows for years and the .m3u8 extension for playlist files works splendidly.

Now I am migrating the Minimserver to Linux (Turnkey - Debian 8), along with the data and playlists from the Windows environment. Minimserver will find and serve up all of these files, no problem. The playlists with special characters work for most files, but some characters seem to cause problems and the Minimserver log on scanning says things like "Error: playlist Music/_Playlists/StrangeCharacters.m3u8: unknown folder for ../Rokia Traoré/Bowmboï/01 M'Bifo.m4a". Other files in the same playlist with special characters in the artist/album name play ok, e.g. "../Toumani Diabate's Symmetric Orchestra/Boulevard De L'Indépendance/02 Boulevard de l'Indépendance.m4a".

Some characters seem to be more special than others. All suggestions welcome.
Marmite.
