I don't think I understand the rationale for using a face. It sounds
like a subset of the general case, and why would someone want this
alignment only for one special face?
With alignment (in terminal):
However, I generally use variable-pitch everywhere else in a Org file. Because variable-pitch are generally prettier.
Using a face also means that the same characters from a larger font
will not be aligned.
For me personally, that’s ok. I can just use a smaller font.
But again, I just want to know if such a feature exists or is easily hackable. If not, I can live without it. Clément’s idea seems doable, though. You just need a local variable that maps glyph’s unicode to the intended width, if I understand him correctly.
