Songs with UTF-8 characters are ignored in playlist

Hi,

I have created an m3u8 playlist in which some songs have UTF-8 characters in the song name or in the path. After copying the playlist file to my Sansa Clip Zip, the playlist does show up, but the songs with UTF-8 characters are missing in the list.

Is this a known problem?
I would be very thankful for any help.

Details:

Device: Sansa Clip Zip, firmware version V01.01.01P

I use the player in MSC mode. My music is organized in /MUSIC folder as
/MUSIC/<artist>/<album>/<song>

The playlist (file extension: m3u8) is copied into /MUSIC folder and looks like this:

#EXTM3U
#EXTINF:<length>,<title>
<artist>\<album>\<song>
#EXTINF:<length>,<title>
<artist>\<album>\<song>
#EXTINF:<length>,<title>
<artist>\<album>\<song>
