Okay, so I figured out how to compile your version of ttf2pt1 (I just 
needed to chmod +x the unhtml script to get the make to complete) and 
now have things more or less working. One mystery still remaining is 
that when I generate PDFs using Cochin, the font I got from my Mac and 
converted from .dfont to .ttf using fontforge, it works except when I 
render the string "hello, world!" it comes out as "helloworld". Strange. 
But it works fine using Gentium with .ufm files produced with your 
ttf2pt1. So I'm going to assume something went awry with fontforge.

Using Gentium I still have two problems. One is when I try to include 
the characters U+6e05 and U+6167 (Chinese characters) it succeeds in 
rendering but the characters are not displayed. Is that becauseGentium 
doesn't support those characters?

And finally, when I try to run unicode-hello using Gentium on the full 
*unicode-test-string* I get this error.
