Out Of The Box full PDF internationalization
PDF files should be generated properly in all supported languages out of the box. There is a big problem with nonenglish characters in PDF files.
For now nonenglish users have to download tcpdf.rb and utf-8 fonts to make use of generated pdf's. I think it is unacceptable for such good project like Redmine.
It would be great to see tcpdf.rb and FreeSans font in next Redmine release.
