On: Ligatures in programming fonts: hell no (2019)

I don’t understand the relevance.

[nitrogen → avgcorrection]

The displayed width alone is not enough information to tell a ligature from a single character.

I was under the wrong impression that “double width” was only a property of some codepoints that were effectively double width variants of the printable ASCII symbols, for use in East Asian contexts. But now I see that there is a combining codepoint, so codepoints in general can be made “double width”. So this does indeed seem relevant.

Check boxes and stuff occupy about a character- width-and-a-half when pasted into Notepad++ set to use Lucida Monospace.
