How can I properly convert a character, say, first one to
upper case in a unicode correct manner?
That would depend on how you'd define correctness. If your
application needs to support "all" languages, then (depending
how you interpret it) the task may not be meaningful, as some
languages don't have the notion of "upper-case" or even
"character" (as an individual glyph). Some languages do have
those notions, but they serve a specific purpose that doesn't
align with the one in English (e.g. Lojban).
In which code level I should be working on? Grapheme? Or maybe
code point is sufficient?
Using graphemes is necessary if you need to support e.g.
combining marks (e.g. ̏◌ + S = ̏S).
Uppercase and Lowercase gets even more funky with Turkish.
