🎯 Subject of the issue

This is the same issue as Mono fonts have same family name as double-width fonts, which was fixed on all other platforms than Windows.

On Windows, if you have both variants installed, it randomly chooses one of them, which probably makes both variants unusable.

🔧 Your Setup

Windows 11 The font does not matter but I have mostly been testing with FiraCode NF

This will be fixed by #717 (former #706).

(This is an obvious (*) error in font-patcher, but because the naming is additionally off in a lot other regards, this ended in a rather big PR, which probably will unfortunately take time to be pulled...)

(*) When you look on the code that adds it, you go ... WAT??!:

          if self.args.windows:
            # do stuff
          else:
              familyname += " " + projectNameSingular
              if self.args.single:
                  familyname += " Mono"

So maybe ~~this~~ the following was intended? But then the family name length check would be corrupted :grimacing:

diff --git a/font-patcher b/font-patcher
index f8ea7880..3d3770de 100755
--- a/font-patcher
+++ b/font-patcher

                 familyname = familyname[:maxFamilyLength]
         else:
             familyname += " " + projectNameSingular
-            if self.args.single:
-                familyname += " Mono"
+        if self.args.single:
+            familyname += " Mono"
 
         # Don't truncate the subfamily to keep fontname unique.  MacOS treats fonts with
         # the same name as the same font, even if subFamily is different.

But as there are a lot other issues, I believe tackling this one issue is not making much difference anyhow.

Sounds good, thank you 👍

After some cleanup and sorting we get the following table. The classic Family/Subfamily is broken, but at least the Nerd Font Mono and the Nerd Font have different family names, which is what this Issue was about.
