The comments in SpecialCasing.txt were changed in 5.2 to include
Titlecasing U+0345, not just uppercasing, and that confuses me. It says
that it needs to be moved after all other marks on the preceding
character. That makes sense to me, because it stops being a mark at
that point, and becomes a (separate) capital iota.
But I don't understand the titlecasing part. Is it meant, when
titlecasing the base character the iota subscript is combined with?
That would also make sense, but then I would think it should move and
become a small letter iota instead, U+03B9.
Or is it meant when the mark is in isolation, not combined with a base
character. This can happen only after a few characters in Unicode, such
as a newline or zero width space. And then I don't understand what
would be done. If ordered properly, in such a situation, any marks in
this isolation situation would already be in front of the iota
subscript, as they all have ccc less than it. Would it then become a
small letter iota?
