For the upcomming version FB 1.5, removing the PDF function should be considered seriously according to me.

If FB 1.5 is aiming to be compatible with Joomla! 1.0, but to work in legacy mode with Joomla! 1.5, it should either implement a new method of PDF generation that works with all languages or better being removed.

I was playing before with Joomlaboard and tcpdf and I was able to make it work in most of the cases. The problem is, that tcpdf is 10 MB
