Arabic script in PDF created by UFPDF

Question

Hello,

I have issues with Arabic script inside a PDF document created by UFPDF, that is an extension of FPDF that supports unicode fonts. I have correctly converted Arial font to the format waited by UFPDF, and I have no issue with Unicode special characters in other languages (e.g. French, Spanish, German, etc.)

The single characters of Arabic script are not shown from right to left, but from left to right and it splits as single chars.

E.g.: مدرسة (school) is shown like ة س ر د م

How to handle?

Thanks in advance
