Linux Debian (Testing).

I've had many problems in the past with international characters, and
many times I've tracked them back to font issues -- change the font, and
the problem goes away.  AFAICT, Monodevelop uses the same font for the
main interface as it does for the output window, so this eliminates this
scenario. (Someone please correct me if I'm wrong.)

Since we have eliminated a font issue (?), this suggests that something
between your mono program and the output window is squashing the output.

Good. This means that mono I18N is not fundamentally broken on the
Mac.  ;)

What happens when you cat the contents of either your source code or the
test file to the terminal?
