I'll add that option for the next release. When I've it ready I'll send it to you first for testing.

Yes, you were right. When using the font arialuni.ttf, the arabic letters
and diacritics are all displayed correctly. I guess I was mistaken in
believing diacritics are not being handled. Thank you for that.
There is another issue though. We are using JasperReports to generate PDF
documents and require that numbers be displayed in arabic as well, using
hindu digits (\u0660 - \u0669). Currently, a change was made in
JasperReports that detects english numbers (arabic digits in the range
\u0030 - \u0039) and substitute the hindu equivalent. However, it would be
preferable if this were handled within iText (is this already happening?),
possibly by setting a new parameter, similar to "runDirection", that
determines whether numbers are displayed using either context, hindu or
arabic digits.
Any thoughts with regards this issue??
hope you have a merry christmas.
Ayman
