Thank you very much it all works fine now, I downloaded and installed the font in http://archive.ubuntu.com/ubuntu/pool/main/t/ttf-wqy-zenhei/ttf-wqy-zenhei_0.5.23.orig.tar.gz, as you advised. Then i deleted the fontList.cache de matplotlib to force its updating, and ran the script with """ fontname="WenQuanYi Zen Hei" """
I can now display the characters and save the plots as pdf. Thanks a lot for you wise help, i learned a lot.
