Re: Arabic & Arabic Extended Languages have 4 or 2 Glyps for
In fact, the best option is probably not exactly either:
Map the glyph for the isolate from the cmap using the Unicode
value in the Arabic block; if you use glyphs that correspond to
characters in the compatibility areas (>= U+FB00), then also
map these glyphs from the cmap using the Unicode values in that
range. For any other glyphs, however, do not map them directly
from the cmap; i.e. don't assign them to *any* Unicode value,
PUA or otherwise. These glyphs should only be accessible using
OpenType substitution tables.
You'll be able to create OpenType tables using a tool that MS
will be making available soon - VOLT (Visual OpenType Layout
Tool). Check out http:
//www.microsoft.com/typography/creators.htm for further
details, and/or join the OpenType list.

Subject: Arabic & Arabic Extended Languages have 4 or 2 Glyps
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?
2- Ignor Compatability Area codes and assinge new codes from
Wish you all the best.
