Hi;

I am developing a Unicode base font for Windows 2k, the font have Glyps for
4 Languages i.e. Pashto, Farsi, Urdu and Arabic. Arabic & Arabic Extended
 Languages have 4 or 2 Glyps for one letter i.e Isolated, Intial, Middle,
Final Forms.

Therefore, I assigned the Unicode Code to the Isolated form and planning
to use Private Use Area for others, but there are some of the Glyps found in
"Arabic Presentation Form A" compatablity Area which confused me that:

1- I should use Glyps found in "Arabic Presentation Form A" and
assing onthers values from private use Area?

or

2- Ignor Compatability Area codes and assinge new codes from
Private Area?

Wish you all the best.
