[racket] text/font not rendering symbol fonts on WinXP

If you want to use, say, α, then you need an actual α in the string, not an "a".

I don't know how the dingbats work, but certainly that's how it works
for characters that are in the unicode character set.

(You can type those characters by using their LaTeX equivalents and
then hitting control-\ or alt-\ (depending on the platform).)
