Expected Behavior

I don't know is this actually a bug of terminal, or should you solve this, but as I tested in lervag/vimtex#2254, the bug only occur in windows terminal through ssh or in wsl2, and will not occur when using native vim or using X server. So I decided to post this issue here.

Actual Behavior

Found reason of this: Terminal has bug displaying char 𝓣 -- bold mathcal characters, and possibly the whole family. Just paste cuple of the char into terminal you'll see the bug effect. One can get a list of such symbols at https://www.wikiwand.com/en/Mathematical_Alphanumeric_Symbols

I use font FiraCode NF, bug same issue will occur also in Consolas, JuliaMono, Cascadia Code, etc.

I'm sure this is some subset of #8000, but I don't know exactly which...

[zadjii-msft]

Probably the #11756 bit so I'm just gonna call this a dupe. Thanks!
