I have used MP3tag to tag hundreds of files always with the same default settings mostly with info from Freedb or amazon. All the tags are the same english characters when viewed in MP3tag or WMP10 but when I load songs (in folders) onto my MP3 Player (a cheap S1 type) some of the tags are displayed as russian or greek characters. The whole album or folder is displayed like this not just odd files so it must be some thing to do with the tag encoding.
Viewing these files/tags in MP3tag and looking at the properties they are no different to the files with tags that display correctly on my MP3 player.
How can put this right and stop it happening in the first place.
