Seeing if a string will "fit", under various meanings:
* wrapping (like 80-column console lines)
* fixed-width fields (like ID3v1)

Neither of which are things that are applicable at codepoint level :)

I've never seen anything best done at codepoint level.  Comparing,
rendering, and storing text all are done at different non-codepoint
levels.
