Genre tagging: using available tag and order sorting

[alan9990]

Ah well...

This is why I'm struggling a bit to understand.

I thought that the ID3v2.4 standard, as opposed to ID3v2.3, allows ANY valid tag field to use a NUL separator??

Did I get this wrong?

However, am now on the trail to a solution... it's my tag editor itself that needs to "know" what a NUL is?!

I'll go and read more docs and see if that's in there.
