I'm the not so proud owner of a Sony Ericsson W810i walkman phone. As a Greek national I have tons of mp3 with Greek tags, encoded in ISO-8859-7 or Windows-1253 encoding. Unfortunately, my phone's music player doesn't display properly mp3 files with Greek tags, it suffers from mojibake. In the options menu of Mp3tag there is an option to enable ID3v2.3 ISO-8859-1.
Is there a way to have Greek tags but not Unicode tags?
