Problem with bold fonts

What happened?

Emacs does not use (some) bold fonts.

What did you expect to happen?

Emacs uses bold fonts when required by the 'bold face attribute.

Steps to reproduce

  1. Use, for example, (setq doom-font "-*-Fira Code-*-*-*-*-14-*-*-*-m-*-*-*") or (setq doom-font "-*-JetBrains Mono-*-*-*-*-14-*-*-*-m-*-*-*)".
  2. Check bold font, for example, an Org headline.
  3. Observe the font used (e.g., with SCP u g a).
    ftcrhb:-JB-JetBrains Mono-*-normal-normal-*-14-*-*-*-m-0-iso10646-1 (#x14C)
    (notice the width type normal, although it should be bold).

Fonts are correctly installed here. I can see all width types using describe-font. I can even set an Emacs-wide bold font using, e.g., (setq doom-font "-*-JetBrains Mono-bold-*-*-*-14-*-*-*-m-*-*-*)".

Even better, the bold fonts are used when I use a font without ligatures, for example, Fira Mono instead of Fira Code: (setq doom-font "-*-Fira Mono-*-*-*-*-14-*-*-*-m-*-*-*")

I am confused.

I’m also experiencing the same problem.

For your reference, I have created an issue at the GitHub repo:

#4

FYI, rendering of bold fonts works again here. No idea what the problem was.

#5

After a recent Nixpkgs and doom sync -u update, the problem is back.

#6

Updating Emacs to the unstable version solved this issue. Weird that font problems make it to the stable version…
