For other charsets, I'd say Google to find them. www.gamingw.net has a lot of charsets as well, but some have to be resized (like the Blacksmith one). Also try www.phylomortis.com for other random stuff. Other than those major sources, you might actually have to make some stuff yourself..

As to demos, I did upload a class change demo recently to show a small CMS for.. changing classes. You might have to copy/paste the link if hotlinking is disabled.
