As far as I understand, the font limitation applies up to tesseract 3.02. Major changes to training are currently in the works in SVN for 3.03 (not fully released yet - hence you see large number of fonts for english traineddata but not for others). The other languages traineddata maybe forthcoming in future.
Ray/Zdenko/Nick may be able to give an idea of expected timeline for release.
