This is where you're still not getting the point.

In English, the difference between italic A and upright A is a font
choice.

In Cyrillic the difference between т and m is also a font choice.

You're trying to say that т and m must be different codepoints because
they have different shapes.  That's no different from saying that italic
A and upright A must have different codepoints because they are
different shapes.

If you say that upright A and italic A are a font choice, then you must
also admit that the difference between т and m are also a font choice,
and therefore т and m must share the same codepoint.

So, which one is it?  You can't have it both ways.


T
