Subject: [PATCH] Hopefully slightly saner handling of character entities in
 links; now will use UTF-8 characters on a UTF-8 wiki for the Latin-1 named
 entities; this prevents corrupt in-wiki links for cases such as [[Wei&szlig;
 kreuz]] or [[Br&ucirc;ker:Foo]]. There is a small chance this will harm
 interwiki links to latin-1 wikis that don't accept UTF-8 incoming URLs, but
 on balance this is a lesser harm. Raw bytes in such links can still be used
 (%XX) if need be.

This shouldn't change behavior on Latin-1 wikis.
