Ubuntu Nerd Font Regular showing up as Condensed.

🎯 Subject of the issue

Experienced behavior:
The font Ubuntu Nerd Font which should compare against the regular Ubuntu font has the style Regular show up as Condensed.

The app I used to display the following is from the gtk font manager.

The following font belongs to the system and is what I expect.

---

The Ubuntu Nerd Font installed locally shows Regular as Condensed.

Incidentally, there is a Ubuntu Condensed specific font that isn't represented in the Nerd Font set. I have no need for this font, but I thought I'd point it out since this specific font has been rolled-up into a style in the base Ubuntu Nerd Font (which makes sense).

Expected behavior:
That the Regular style and the Condensed style should both be distinct. The Ubuntu Nerd Font Regular style should have the same style as Ubuntu Regular.

🔧 Your Setup

• Which font are you using (e.g. Anonymice Powerline Nerd Font Complete.ttf)?
  • UbuntuNerdFont-Regular.ttf
• Where did you get the file from (download link, self patched, source downloaded from link...)
• Which terminal emulator are you using (e.g. iterm2, urxvt, gnome, konsole)?
  • This problem showed up in dunst notifications (not terminal). But is problematic in any other app that uses the font.
• Are you using OS X, Linux or Windows? And which specific version or distribution?
  • Linux (ArchLinux)

Can reproduce

Naming looks like this

Lets see...

[Finii]

🤔 Why does it list 9 variations on your system and only 7 on my? I just copied all fonts over?

Light and Bold is missing??!

Even more strangeness in the Propo section

Correct in writer

When I switch from User to All it shows 9 instead of 7?
This thing has a bug.

And why do 'System' and 'User' not sum up to 'All'?

Anyhow, there is a problem with the Postscript Name it seems.

Should be detected as width variation 🤔

But wrong using width as weight?

This was also the with v2.3.3, the last change for v3.0.0 did not in principle change that.

Correct as Adobe spec, the example has condensed in it:

---

Well, the original Ubuntu font makes the Condensed font a width: Regular, which is of course questionable and which is corrected by the FontnameTools (because they create the naming from scratch). At least it contradicts the Adobe spec.

For example Noto also puts Condensed 'after the dash' (as Nerd Fonts does)

Unpatched Noto Sans ... the Condensed is listed with the main widths...

Ubuntu unpatched has a different (somehow non-conforming) approach here. Nerd Fonts strives to create conforming fonts.

Incidentally, there is a Ubuntu Condensed specific font that isn't represented in the Nerd Font set. I have no need for this font, but I thought I'd point it out since this specific font has been rolled-up into a style in the base Ubuntu Nerd Font (which makes sense).

So this is not a problem.

But still, there is a problem, the rendering is taking the wrong font.
(And 'User' misses some)

[Finii]

Now comparing with Noto only for wrong rendering (and maybe missing in 'User'):

Naming is comparable to NotoSans

We do not add -Regular to the PS name. Is that correct?
We do not add Regular to the FullName, which is the recommended approach iirc.

A look at fontconfig:

$ fc-list | grep '(UbuntuNerdFont|NotoSans)-(Regular|Condensed)\.'
/home/fini/.local/share/fonts/NotoSans-Regular.ttf:         Noto Sans                              : style=Regular
/home/fini/.local/share/fonts/NotoSans-Condensed.ttf:       Noto Sans,Noto Sans Cond               : style=Condensed,Regular

/home/fini/.local/share/fonts/UbuntuNerdFont-Regular.ttf:   Ubuntu Nerd Font                       : style=Regular
/home/fini/.local/share/fonts/UbuntuNerdFont-Condensed.ttf: Ubuntu Nerd Font,Ubuntu Nerd Font Cond : style=Condensed,Regular

Looks the same.

Ah

Why is it not picking up the width specifier...

"Condensed" is also missing in the rendered example text on the right 🤔

Obviously not a problem of the abbreviation in the PS name

---

Very strange. Had a look at FontManager's source and it get all information from fontconfig, and THAT reports the correct style(s).

[Finii]

Built from source (github HEAD), same problem

Stuffing sourcecode with debug things...

Ok, it comes out of fontconfig:

$ fc-list -f '%{file}: %{family} | %{style} -- %{weight}:%{width}\n' | grep UbuntuN
/home/fini/.local/share/fonts/UbuntuNerdFont-Condensed.ttf: Ubuntu Nerd Font,Ubuntu Nerd Font Cond | Condensed,Regular -- 80:100
/home/fini/.local/share/fonts/UbuntuNerdFont-Light.ttf: Ubuntu Nerd Font,Ubuntu Nerd Font Light | Light,Regular -- 50:100
/home/fini/.local/share/fonts/UbuntuNF-Regular.ttf: Ubuntu Nerd Font | Regular -- 80:100
/home/fini/.local/share/fonts/UbuntuNerdFont-LightItalic.ttf: Ubuntu Nerd Font,Ubuntu Nerd Font Light | Light Italic,Italic -- 50:100
/home/fini/.local/share/fonts/UbuntuNerdFont-Medium.ttf: Ubuntu Nerd Font,Ubuntu Nerd Font Med | Medium,Regular -- 100:100
/home/fini/.local/share/fonts/UbuntuNerdFont-Bold.ttf: Ubuntu Nerd Font | Bold -- 200:100
/home/fini/.local/share/fonts/UbuntuNerdFont-Italic.ttf: Ubuntu Nerd Font | Italic -- 80:100
/home/fini/.local/share/fonts/UbuntuNerdFont-MediumItalic.ttf: Ubuntu Nerd Font,Ubuntu Nerd Font Med | Medium Italic,Italic -- 100:100
/home/fini/.local/share/fonts/UbuntuNerdFont-BoldItalic.ttf: Ubuntu Nerd Font | Bold Italic -- 200:100

It should be

#define FC_WIDTH_CONDENSED	    75

Ah, Ubuntu forgot (?!) to set the width of the font to 'condensed' 🙄

[Finii]

After fixing it shows correctly on my self-built FontManager, but not-at-all anymore on the Flatpak.
Maybe some caching problem ;-)

That the number of fonts, although installed in the user directory, differs between 'all' and 'user', is still a mystery for me. Any ideas?

Also '9' now in 'User'.

Creating some PR...

Thanks for reporting!

[ffernand]

👀 Oh wow... I did not expect to wake up to some in-depth reporting on this PR! 🎉

Incidentally, I can't explain why you were able to get 7 vs. 9 variations depending on whether you filtered by All or User. I was able to see 9 variations from both filters. I'm using the stock Ubuntu Nerd Font from the zipfile downloaded from the github website and the version of font-manager I used is v0.8.8 on my ArchLinux box.

Much appreciated @Finii for all the hard work!

I just write down all I do in case I'm interrupted by kids or day work or ... ;-)

I guess it has something to do with being a Flatpak. They mention something one would have to adjust with Flatseal, which I of course did not :-D
Always self-build from source 👍 😁

Much appreciated @Finii for all the hard work!

Thank you :-)

We do not add Regular to the FullName, which is the recommended approach iirc.

This has not been answered! 😠 Got sidetracked.

[Finii]

Ah, looking at Iosevka, they do the same (not add Regular in both places.

Adding Regular to the FullName is optional - it is not recommended to not add, I believe now. See [1].

When it is left off, it is also left off of the PS name.

Here our list which fonts do what:

    @staticmethod
    def is_keep_regular(basename):
        """This has been decided by the font designers, we need to mimic that (for comparison purposes)"""
        KEEP_REGULAR = [
            'Agave',
            'Arimo',
            'Aurulent',
            'Cascadia',
            'Cousine',
            'Fantasque',
            'Fira',
            'Overpass',
            'Lilex',
            'Inconsolata$', # not InconsolataGo
            'IAWriter',
            'Meslo',
            'Monoid',
            'Mononoki',
            'Hack',
            'JetBrains Mono',
            'Noto Sans',
            'Noto Serif',
            'Victor',
        ]
        for kr in KEEP_REGULAR:
            if (basename.rstrip() + '$').startswith(kr): return True
        return False
