Using that dll fixed the problem on Windows XP 32bit! Using the 64-bit one on Windows 7 64-bit didn't work, though. Also, I was able to test out text/font with a symbol font on OS X 10.8.2, and it also would not render the symbol font. I found somebody who had made TeX fonts for byzantine neumes, and using mftrace I was able to generate a unicode-compatible TTF. That works like a charm on all platforms, even though the standard letters have been replaced by symbols. I found out that there's actually space reserved in the unicode standard for byzantine neumes, but nobody has yet done the work of making such a font. Thank you again for your help! <div class="gmail_quote">On Tue, Nov 27, 2012 at 11:21 PM, Matthew Flatt <<a href="mailto:mflatt@cs.utah.edu" target="_blank">mflatt@cs.utah.edu</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5">At Sat, 24 Nov 2012 10:44:36 -0600, Robby Findler wrote: > On Sat, Nov 24, 2012 at 10:10 AM, Matthew Flatt <<a href="mailto:mflatt@cs.utah.edu">mflatt@cs.utah.edu</a>> wrote: > > Unfortunately, patching Pango means compiling it myself for Windows, > > which is a tedious task that I had so far avoided.

I thought that my recent experience with mingw32/mingw64 to compile GMP and MPFR might help me compile Pango, but it seems that I'm still not expert enough. Meanwhile, it occurs to me that it's easy to just patch the binary --- a one-byte change should do it. Clement, can you try one of the following (the one matching your Racket installation) as a replacement for "libpangowin32-1.0-0.dll" in the "lib" directory of your Racket installation? Win32: <a href="http://download.racket-lang.org/libs/10/win32/i386/libpangowin32-1.0-0.dll Win64" target="_blank">http://download.racket-lang.org/libs/10/win32/i386/libpangowin32-1.0-0.dll Win64</a>: <a href="http://download.racket-lang.org/libs/10/win32/x86_64/libpangowin32-1.0-0.dll" target="_blank">http://download.racket-lang.org/libs/10/win32/x86_64/libpangowin32-1.0-0.dll</a> </blockquote></div>
