Renaming sal_Unicode to a less misleading name?

[Khaled Hosny]

I’m wondering if it is possible to rename sal_Unicode, which is actually
a unsigned 16 bit integer and thus can’t fit any Unicode character, to
some less confusing name like sal_Ucs2 or even just use sal_uInt16 (but
please not sal_Utf16 which would give the illusion that surrogate pairs
and handled in a special way which I don’t think is true).

I count only ~7000 usages across the code base, so that is not such a
huge task. It would be even a better idea to access its current uses, as
I have my doubt that it is always really what people who wrote such code
thought it is.

Or is it part of some public API and should stay as such?
