Or perhaps is it a side effect of the compatibility mapping and the
deprecated uses of them.
BTW these mappings appeared with 3.0.

My idea is that it should produce a small cap k.
Since this character does not exist in Unicode (even with combining
character as far as I know), the question is how should it be encoded.

On the other hand, about the capitalization of , I do not know.
"Full cap small letter mu" is not a existing glyph ;-), using M
would be definitively wrong (the value will be multiplied by 1000),
and which have a descender does not look good in a full-cap text...
I believe I saw once a raised in such a case, and I found it ugly.
