If the subject is all you have read of this thread, then you are 
definitely misunderstanding.

This is nothing to do with psgml (which is not part of Emacs), or nxml. 
AFAIK psgml does nothing about encoding, as sgml files are not 
necessarily in any particular encoding. Nxml had some code which as far 
as I understand is similar to what I was proposing as a solution here. I 
removed that code shortly after it was merged into Emacs since Emacs 
already had code which seemed to do the same thing for XML files, 
regardless of mode. It is only now that I found out that the code in 
Emacs is overly simplistic, forcing UTF-8 even against users' wishes.
