Concealing subscript letters stopped working

ConnerRose commented 3 months ago

Description

I noticed recently that subscripts using letters are no longer being concealed correctly. I.e., for $v_n$, the subscript n is replaced with an empty box (I think indicating that the character is not found). Can anyone else confirm that this isn't just a problem for me?

Steps to reproduce

Edit a .tex file with concealing on.

Expected behavior

Subscript letters to be concealed as a smaller version of that letter.

Actual behavior

Subscript letters concealed as (what I think to be) missing character icons.

Do you use a latexmkrc file?

No

It seems that concealing works for some letters and not other. For instance, $v_j$ works as expected.

This is most likely a problem with your terminal font. I.e., it seems you are using a font that does not support all the various symbols. Each subscript and superscript symbol is a specific element of the font, so you will want to use a font that has support for a lot of symbols.

This is how things render in my terminal (rxvt-unicode) with the JuliaMono font (https://juliamono.netlify.app/):

I've written a little bit about fonts under :help vimtex-syntax-conceal. I believe this should be sufficient input for you to figure things out; if not, then I propose you do some search on how to configure your terminal with different fonts.
