🎯 Subject of the issue

Experienced behavior:

Patched Fira Code shows different height from original font (and older release 'Fura Code') on Windows Terminal when set to specific font size. Happens with both regular and retina variant when font size is set to 9.

Expected behavior:

Patched Fira Code should match the original font height.

🔧 Your Setup

• Fira Code Regular Nerd Font Complete Windows Compatible.ttf
  • Tried source downloaded from link and self patched.
• Windows Terminal (release and preview)
• Windows 11

Suspect #761

Maybe that should also go into 2.2.0 🤔

@Finii I can try this branch and report back

[brneor]

@Finii patched the font using the suggested branch and everything looks almost fine now! Tried both regular and retina variants.

FiraCode NF Retina still looks of in bold (but also old FuraCode).

Regular:

Retina:

@Finii @ryanoasis this got partially fixed in a recent release. The bold issue in "Retina" variant still persists. Just FYI.

Thanks for the feedback.

Marked this 3.0.0 to not forget it 😬

Ah, I think now I get it...

You know that Retina is just a weight, like Regular, Light, Bold, or Heavy?

Plus only Regular, Italic, Bold and BoldItalic form a classic RIBBI group.

If you use Retina the application does not have a Bold version of that. It either has to create one on the fly (also done with missing Italic variants that are Obliqued automatically if need be), or you need to have a separate setting for 'which font to take for <Bold>'.

From the images it seems that Windows Terminal takes some backup font instead.

As there is no Retina-Bold (whatever that would mean, its the same as to say the weight is Light-Heavy?!), there is nothing we can do here.

With some terminals you can adjust all 4 fonts individually in the settings. But I guess that is not possible with Windows Terminal. What one could do is creating a RIBBI group from Retina and Bold, but that would involve changing the font's metadata.

Then I tried to output bold text in the ordinary Windows Terminal and could not manage it at all. There is the 'Use really bold and not bright color' setting, but that still did not work.

So I can not really reproduce, but Retina just does not have an associated 'Bold', whatever the Terminal is doing in your case. What does it do if you select a script font that does not have bold neither italic?

I fear the problem in your case is that you use Fedora in this Windows Linux Subsystem, and that muddles up all the font engines (I guess).

I take this off 3.0.1 again, and am inclined to close it. But maybe you have more information.

@Finii thank you for the explanation.

I tried to reproduce the issue again so I could provide more information but looks like it does not happen in v3.0... But IIRC, it happened in Windows Terminal when using just powershell.

[Finii]

I searched Windows Terminal and there we several (closed) Issues about BOLD, maybe it was a bug there.

So I close this now, feel free to reopen if it re-surfaces :-)
