The former

max, but the latter is a pretty big project (cf. Unicode
line-breaking
algorithm, which is one of the TR's).
It'd be good enough to duplicate the existing behavior, which
is to treat decoded unicode characters as one column.
Code points aren't equivalent to characters. They're not the same
thing in most European languages, never mind the rest of the
world. If we have a line-wrapping algorithm in phobos that works
by code points, it needs a large "THIS IS ONLY FOR SIMPLE ENGLISH
TEXT" warning.
Code points are a useful chunk size for some tasjs and completely
insufficient for others.
