As we discussed in #9490

Yeah -- this is an unfortunate outcome of us summing up the number of cells covered by the codepoints comprising a character and then trying to render its glyph in those cells. #8000 will be a crack at making us support glyphs that take more than 2 cells. Measurement is left for a future workitem. That future workitem is #1472, which tracks getting us capable of properly measuring the space occupied by a stream of codepoints and rendering it.

I too wish that there were a separate mode for letting the Terminal figure out how wide things are without having to disagree on wcwidth/wcswidth, but I think that ship's sailed. ☹️
