There are differences in the shape of these two letters in isolated or
final form that has made Unicode encode these as two different letters.
The Iranian Standard ISIRI 6219:2002 "Information Technology -- Persian
Information Interchange and Display Mechanism, using Unicode", *requires*
using U+06A9 ARABIC LETTER KEHEH for the Persian Kaf because of its
Persian shape and Unicode's recommendation.
Please tell your staff to use U+06A9 KEHEH for the Persian Kaf, if they
wish consistency with other Persian information encoded in Unicode on the
web.

Microsoft's "Farsi" keyboard is right to include KEHEH as the main Persian
Kaf. The Iranian keyboard standard ISIRI 2901:1994 has both KEHEH and KAF
on the keyboard (the later on a shifted position), to faciliate Arabic
text entry using the Persian keyboard.

There is a web page and two mailing list on Persian Computing matters.
