Thanks a lot for help but I think it's from my database language so It can't show in Thai. Then I have to find new ways to solve this problem. Thank you very much for good add-on
I 've tried to add font follow tutorial 7 at fpdf.org already but I don't know , Where is the mistake again? Because it can't work. For example that I try; add font tahoma in fpdf.php file.
Thank you for your reply.
