Problem with link to playlist with spaces

[leruetkins]

kaRadio32 does not accept playlists that contain spaces or other non-standard characters (for example, Cyrillic), it's shows "No data". But if the playlist itself contains link with such characters, then everything is played.
I tried such link as:
http://192.168.0.172:3000/mp3-files/%D0%BA.radio.m3u
Or
http://192.168.0.172:3000/mp3-files/1%202.radio.m3u
Or
http://192.168.0.172:3000/mp3-files/к.radio.m3u
Or
http://192.168.0.172:3000/mp3-files/1 2.radio.m3u
