This is a regular expression problem. The proper regular expression
has a lowerthan-character, the string "filename", and a
greaterthan-character immedately after the capital P. It might be a
problem related to the email-system, which might strip away this
string, since it is html-like (just a wild guess). I include the
proper regular expression again ... maybe you can properly extract it
now:

    pattern = re.compile(r"\((?P<filename>[^)]+(\.fd|\.def))\)")

(You can also take a look in the CVS (using the ViewCVS for example),
where the proper regular expression is now inserted in the file
pyx/text.py. Note also, that the P<filename>-part is not changed
compared to the version you can find in pyx/text.py in the 0.8.1
source distribution of PyX.)

Beside that -- this is another but also important issue -- you could
try whether your LaTeX system is able to handle utf8 input encoding.
You need the ucs-package installed for that and than a file like

    \documentclass{article}
    \usepackage{ucs}
    \usepackage[utf8x]{inputenc}
    \begin{document}
    ... some unicode characters in utf-8 encoding ...
    \end{document}

should be smoothly processed by latex.

HTH,


André
