I decided to recently start parsing some of my mp3 files to see what type of tags they had. Then I ran across one with a strange formatting in the TIT2 frame, which is a title. It had the name of my song, but each letter was separated by a 0x00 byte. None of my media players have trouble reading this. Any suggestions to what the problem could be?

Sounds like it was stored in UNICODE. a "wchar_t" is two bytes wide instead of one. The world runs on UNICODE now, so you may wind up with more files like this one in the future, unless you use an old Windows 9X application to edit them. I'll post a link below to some information that helped me get started with UNICODE in my C++ programs a while back. Maybe it can explain this to you.
