[otrs] Does anybody have used any none-European language in graphical reports?

Hi everybody, Some kind of reports (stats) are generated as graphic files like bar charts or pie charts. In these reports there is some texts to describe the report. I'm wondering if anybody have used non-European languages like Japanese, Persian (Farsi), Arabic, Hebrew, etc in these reports? In my case I'm using Persian (Farsi) but rendered graphics files display the text incorrect. A full history of problem is recorded here (a sample picture also included): http://afsharm.blogspot.com/2009/04/otrs-gd-library-and-persian-support.html Does anybody have any experience?
