not a font style. its in the bitfields. reasoning for fontstyle flags ios that
they can affect cell size (eg bold is wider than not bold). if you dont ever
plan on supporting bold flags, then no point making cells bigger.

no - need int. wchar_t (16bit) is not enough for unicode. use int.

no. this is at the api level. this is an internal thing/

because the overhead of access (1 fn call per char in the grid per update).
