Ah, ok.  Gotcha.

It's both in Gecko.  We really do try to keep the number of 
special-cases to a minimum.  ;)

I agree that we probably need to standardize this, because I fully 
expect web sites to depend on the ISO-8859-1 bit when all the charcodes 
are < 255.

Well, no.  There's the question of what's least confusing for authors 
too; see my other mail about that in this thread.
