files with ë or é etc do not make it into playlist

[simoncn]

There are two character encodings used for playlist files. A playlist file with a .m3u extension uses the ISO 8859-1 encoding (effectively the same as Windows-1252) and a playlist file with a .m3u8 extension uses the UTF-8 encoding. Most Windows systems use Windows-1252 by default and most Mac and Linux systems use UTF-8 by default.

As you are using a .m3u file extension, MinimServer expects accented characters to be encoded using Windows-1252. If your playlist file has these characters encoded using UTF-8, changing the file extension to .m3u8 should enable the missing items to be displayed.
