AW: [ID3 Dev] 0-termination in text frames

[Paul Taylor]

I think it is unclear and unnecessary unless you are writing multiple 
strings in a v2.4 frame, so i never write them. The disadvantage of 
writing them is that players/taggers that dont realise that this null 
terminater should not be displayed display it as an undisplayable 
character, and also your additional not needed bytes.

Version 2.4 says a 0 terminator separates substrings because every text frame allows multiple strings in 2.4. Well, I don't know if this is a common use-case anyway.
