Hmm, as i understand it right now, a character in guile is never
encoding-specific (and i never suggested making it so).
What i (and Lars, i guess) suggest, is to make guile's list of _named_ 
character literals configurable. Nothing more. Since this is a question
of the _reader_ it won't change anything. Whether i type #\Auml or '?'
(that's an capital 'a' with a german umlaut accent for those non-iso-8859-1ers)
doesn't make any difference to the guile interpreter, or?

Good question! The current state of unicode support makes it impossible to
use guile with XML, i'm affraid :-(
