In 1994 I had a lot of fun designing chess fonts. KnightMares has three rather formal chess fonts. The key layout is a little complicated. To get a piece on a black square, one must use two characters, one for the piece and another that has no width for the blackground.

I wrote a little program for the Macintosh to help set up keyboards several years ago, and if you search for ChessEdit on the internet, you may still find a copy. In addition to making chess boards, some of the pieces make interesting decorations.
