A concern about RIFF INFO tag support and string handlers

[Miyakoda Akira]

Hi everybody.

I'm creating a patch to support INFO tags in RIFF wave files. The patch 
itself is going well, but I have a concern about it. I'd like a second 
opinion.

INFO tag needs a string handler class like ID3v1 and ID3v2 because it's 
common to write INFO tags in local encodings. So, if the patch is 
accepted, TagLib will become to have three duplicate string hanlder 
classes. I think it's not convenient for users and it's the best way to 
create a common base class. Any ideas about it?
