🎯 Subject of the issue

Experienced behavior:

After installing

Caskaydia Cove Nerd Font Complete Regular.otf
Caskaydia Cove Nerd Font Complete Mono Regular.otf
Caskaydia Cove Nerd Font Complete Windows Compatible Regular.otf
Caskaydia Cove Nerd Font Complete Mono Windows Compatible Regular.otf

only the Nerd Font Mono variants are visible in Windows Terminal, when not selecting all fonts.

This is possibly a regression, I believe this had been fixed before.

They ARE selectable with Gnome-Terminal which is also picky sometimes.

Expected behavior:

Can select all 4

Counterexample (old naming engine active)

Edit: Red herring, has nothing to do with naming engine

SIGH

The sourcefont IS selectable with Windows Terminal, but has no Panose??

Edit: It's selectable because the VF has Panose bits, but the same static one has not

WT Preview 1.17.1023.0
Fonts from 2.3.3 release.

I often change settings by editing the configuration file, but everything works through the GUI.

@237dmitry Thanks for the information.

You have the all fonts selected, then it's no problem. But you can not select the font if all fonts is deselected, albeit it should be possible.

And we tracked it down to be a glitch in the Cascadia Code release, see the Issue there (linked above).

Anyhow, added code that autocorrects bad/wrong/missing Panose flags.

[237dmitry]

With unchecked Show all fonts the *.otf fonts are out of view at all.

@237dmitry

Not if they have correct Panose information?
Excatly that was this issue about.

Edit: Remove wrong image

[Finii]

Here, the 4 fonts just created by

$ fontforge font-patcher src/unpatched-fonts/CascadiaCode/Regular/CascadiaCode-Regular.otf --also-windows
$ fontforge font-patcher src/unpatched-fonts/CascadiaCode/Regular/CascadiaCode-Regular.otf --also-windows --mono

("all fonts" still unselected), note version 2.3.3-32

You see, no problem with otf at all.

Edit: Sorry finishing edit only now, because ... I can not work on that Windows machine, it drives me crazy (because it runs in 'Germany' mode which is ridiculous

[237dmitry]

Not if they have correct Panose information?

Sorry, but I don't know what Panose is. *.otf font information is correct in Windows (11) Font Manager. But they are not visible either in the conhost settings or in the WT settings (if the Show all fonts checkbox is unchecked)

[Finii]

Fonts have much more information stored than the Font Manager is able to show. And then there are tables that stem from different companies (i.e. Adobe/Apple/Microsoft as the big ones) that store 'almost similar but different' information.

To cite Yannis Haralambous:

[You] should be aware of the fact that everything pertaining to encodings, and to fonts in particular, is considered to be industrial knowledge and therefore cannot be disseminated, at least not completely. It is hard to imagine how badly the “specifications” of certain technologies are written, whether because of negligence or out of a conscious desire to prevent the full use of the technologies. Some of the appendices of this book were written for the very purpose of describing certain technologies with a reputation for inaccessibility, such as AAT tables and TrueType instructions, as clearly and exhaustively as possible.

[237dmitry]

I looked more closely at the version of the font, it is 2.3.0, I will reinstall it now and answer. I wanted to replace it, but for some reason I forgot, I changed it only in Linux.

Reinstalled.

No difference. OTF invisible.
