How can I properly convert a character, say, first one to upper
case in a unicode correct manner?
In which code level I should be working on? Grapheme? Or maybe
code point is sufficient?
There are few phobos functions like asCapitalized() none of
which are what I want.
I would probably go for std.utf.decode [1] to get the character
and its length in code units, capitalize it, and concatenate the
result with the rest of the string.
