The algorithm, and all that I have seen, convert Arabic characters in the
\x{06--} range to Arabic Presentation Forms A ( starting at \x{FB50} or B
( starting at \x{FE70} ) characters depending on their medial, isolated,
initial, and final values per the Unicode standard.
I am not sure that I understand your point. Isn't this the purpose of the
Arabic Presentation Forms?
I have found several different algorthms that do this but have found none on
CPAN. Note that I may help someone else (who has a simpler module than
mine) to upload his files.
I use the modules when rendering text on images using ImageMagick which
performs no shaping nor bidi algorithm. Without this shaping module many
of the characters are not rendered correctly. It my case the shaping module
is not limited nor misleading but required.
Perhaps, you have a better way?
