From the Fortress wiki:
http://projectfortress.sun.com/Projects/Community/wiki/MathSyntaxInFortress
"""
Support for the full collection of symbols is not widespread yet, but
three fonts offer good coverage:

    * Code2000 many characters, shareware ($5)
    * Everson Mono monowidth, shareware (€25 for 3 computers)
    * Stix fonts comprehensive, integrated with TeX, probably released
later this year.
"""

So there are only three fonts usable for Fortress?  And two require
payment, and one isn't actually released yet??
