the place to look. Squares typically mean that the character you are

Thanks for the last sentence. I had set TTFPATH properly but
I don't know why matplotlib didn't see the ttf fonts in
$HOME/.fonts. I searched gmane and found your article which do apply
If you are sure on both counts, it may help to remove your font cache
(typically ~/.ttffont.cache on linux like systems) and let matplotlib
regenerate it's cache.
No it works all ok!
Thanks a lot.
