I have been writing a mathematical application in Java, and have
written a rendering engine for many different types of equations.  One
problem that has persisted has been the treatment of Greek letters.  It
was trivial to find the unicode values for Greek characters and use
them to render variables with names like pi or sigma, but the default
Greek font on my laptop is atrocious, and other machines don't seem to
have it at all.  I was wondering if anyone knows anything about where
to get a decent, portable Greek font that looks fairly standard.
