I've been playing with Arabic text in Adobe Reader 9.2 and in Foxit and see no sign that either implements BIDI.
Which PDF viewers support BIDI?

Which means, if FOP does BIDI for PDF output itself in order to guarantee proper rendering, each character has to be individually positioned, which bloats the file and could break search and maybe copy&paste too. Or could we simply ignore PDF viewers incapable of rendering r-l text properly? J.Pietschmann
