Unicode/Wide Char Font Support (Cleaner Pull Request) #64
I'm interested in playing with it, though I haven't had the chance to yet. I'd say if you don't have a pressing reason to ditch it, don't. If you do, I can pull it into my repo on a spare branch.
Edit: adding @haggischan to hopefully notify you of this post.
You could use a string class to relieve casting headaches. irrlicht has a really tidy solution: http://irrlicht.sourceforge.net/docu/irr_string_8h_source.html
it's zlib so you'll be able to lift their source.
