We have tested various portable Mp3 players and some of them had problem with UNICODE written tags, so we decided to go with MBCS.
Zortam uses Multibyte Character Set (MBCS).
MBCS is 1 or 2 bytes per character. UNICODE is 2 bytes. MBCS handles foreign characters.
A good example is the Japanese character set. Japanese uses 2 bytes per char
most of languages uses 1 byte per char.
Also Win9X DOES NOT support UNICODE.
UNICODE is better solutions because it always uses two bytes per character but there are some different encoding standards ( UTF16 etc..).
So Zortam is able to read UNICODE tags but it saves data in MBCS (Multibyte Character Set).
