Description
As per #1071, PUA Unicode characters are rendered bigger when there is a space to the right. Most of the time it works as expected, but for some subset of Nerd Fonts characters it gives too small icons. I noticed it for characters with 'nf-md-alpha_*' classes, like 'nf-md-alpha_a' (a.k.a. "", a.k.a. f0aee).
Here is how it looks compared to similar 'nf-md-alpha-***' characters:
PUA scaling in Ghostty
Here is how it looks in Kitty and WezTerm for comparison (they look cramped mostly because my font has very small margins on top and bottom)::
PUA scaling in Kitty
PUA scaling in WezTerm
And here is how it looks in st which doesn't do "render bigger if there is space to the right":
No PUA scaling in st
So my question is is there anything reasonable to be done here?
In particular, I became more curious about this behavior mostly because st without scaling results into more readable icons than Ghostty with this type of adjustment.
