The assumption here is that decomposed characters render like their composed character equivalents, and that working with the former comes with a risk of over-estimating string widths given that we compute them on a per-code-point basis. The regression test added here (한글 vs 한글) is an example of that happening.

This is always going to be an imperfect calculation given how much it depends on differences between each terminals support for variable width characters. Definitely wish there was a better way to do this overall. |
