Oh? What about U+0643 Kaf and U+06A9 Keheh? That case has an interesting parallel to this one. Keheh is specific form of Kaf, much as TH WITH STRIKETHROUGH can be considered a specific form of LEXICOGRAPHIC VOICED TH. The difference is that the distinction embodied by Keheh is generally recognized by a group of common users, while the distinction embodied by TH WITH STRIKETHROUGH is significant only at the level of the choice that an individual publisher chooses to make. ...
In that case, what about U and V? Kaf and Keheh, although originally different shapes of one Arabic letter, are used as separate letters in some languages of Pakistan, and the users of those languages are the group of common users who recognise the distinction. U and V are originally different shapes of one Latin letter, and the distinction between them is also generally recognised by a group of common users, i.e. users of English and most other modern Latin script languages. But do we take U and V as different presentation forms of one character? Should one of them be only in the PUA? Surely not.
