Actual Behavior

I'm warned that I can't find the "D2Coding" font, but I used this font a week ago and it has now been removed from my system.

As you can see, I can't change the font whether I set it via the GUI or change it via the settings.json configuration file.

I tried reinstalling the lower version 1.19.10573.0 and it still has the above problem.

Did you install that font for all users? Or just for your current user/? We've had persistent problems with fonts that aren't installed for all users 🤷

The problem I'm having is that I've selected font A, but Windows Terminal tells me can't find font B!

Could you share your settings.json file/?

@zadjii-msft I believe this occurs because they're using DxRenderer. It gets the font family from the font file here:

terminal/src/renderer/dx/DxFontInfo.cpp

Lines 257 to 313 in 39f9092

	[[nodiscard]] std::wstring DxFontInfo::_GetFontFamilyName(const gsl::not_null<IDWriteFontFamily*> fontFamily,
	std::wstring& localeName)
	{
	// See: https://docs.microsoft.com/en-us/windows/win32/api/dwrite/nn-dwrite-idwritefontcollection
	Microsoft::WRL::ComPtr<IDWriteLocalizedStrings> familyNames;
	THROW_IF_FAILED(fontFamily->GetFamilyNames(&familyNames));
	// First we have to find the right family name for the locale. We're going to bias toward what the caller
	// requested, but fallback if we need to and reply with the locale we ended up choosing.
	UINT32 index = 0;
	BOOL exists = false;
	// This returns S_OK whether or not it finds a locale name. Check exists field instead.
	// If it returns an error, it's a real problem, not an absence of this locale name.
	// https://docs.microsoft.com/en-us/windows/win32/api/dwrite/nf-dwrite-idwritelocalizedstrings-findlocalename
	THROW_IF_FAILED(familyNames->FindLocaleName(localeName.data(), &index, &exists));
	// If we tried and it still doesn't exist, try with the fallback locale.
	if (!exists)
	{
	localeName = L"en-us";
	THROW_IF_FAILED(familyNames->FindLocaleName(localeName.data(), &index, &exists));
	}
	// If it still doesn't exist, we're going to try index 0.
	if (!exists)
	{
	index = 0;
	// Get the locale name out so at least the caller knows what locale this name goes with.
	UINT32 length = 0;
	THROW_IF_FAILED(familyNames->GetLocaleNameLength(index, &length));
	localeName.resize(length);
	// https://docs.microsoft.com/en-us/windows/win32/api/dwrite/nf-dwrite-idwritelocalizedstrings-getlocalenamelength
	// https://docs.microsoft.com/en-us/windows/win32/api/dwrite/nf-dwrite-idwritelocalizedstrings-getlocalename
	// GetLocaleNameLength does not include space for null terminator, but GetLocaleName needs it so add one.
	THROW_IF_FAILED(familyNames->GetLocaleName(index, localeName.data(), length + 1));
	}
	// OK, now that we've decided which family name and the locale that it's in... let's go get it.
	UINT32 length = 0;
	THROW_IF_FAILED(familyNames->GetStringLength(index, &length));
	// Make our output buffer and resize it so it is allocated.
	std::wstring retVal;
	retVal.resize(length);
	// FINALLY, go fetch the string name.
	// https://docs.microsoft.com/en-us/windows/win32/api/dwrite/nf-dwrite-idwritelocalizedstrings-getstringlength
	// https://docs.microsoft.com/en-us/windows/win32/api/dwrite/nf-dwrite-idwritelocalizedstrings-getstring
	// Once again, GetStringLength is without the null, but GetString needs the null. So add one.
	THROW_IF_FAILED(familyNames->GetString(index, retVal.data(), length + 1));
	// and return it.
	return retVal;
	}

The warning pops up if that family name does not match the font name in the settings.

This issue has been solved in two ways:

• DxRenderer does not exist anymore. You can only use AtlasEngine in the latest builds.
• Add support for customizing font fallback #16821 refactored the way we emit renderer warnings, so this can't happen anymore.

@ShaneLee-9 As a workaround you can simply use AtlasEngine until 1.21 is released.

Could you share your settings.json file/?

Hi, this is my settings.json

settings.json

Now that you have AtlasEngine enabled, does the error go away? If it still happens for some reason, please feel free to temporarily use our Canary build (our nightly version): https://aka.ms/terminal-canary-installer

AtlasEngine enabled, but the problem persists!
I installed the Canary version (our nightly version)

Hmm... I see, that's surprising.

Can you please provide a link to the font so I can download it?

Are you certain that this is the exact same font that you're using? It only contains an US English name which is "D2CodingLigature Nerd Font":

There's no mention of "FragmentMono". Do you have a different font installed which is called "FragmentMono"? If so, can you provide a download link for that font as well? I know that Fragment Mono exists, but there's no official "Nerd Font" variant for it.

"D2CodingLigature Nerd Font" does properly show up in Windows Terminal 1.19.10821.0 for me:

Selecting it doesn't result in any error messages for me either. If I manually enter "FragmentMono Nerd Font" the correct font name shows up in the error message:

The root cause of my problem is that I installed the font "D2CodingLigature Nerd Font Mono" about a week ago. One day I removed "D2CodingLigature Nerd Font Mono" from my computer and installed "FragmentMono Nerd Font". Then I wanted to change my Terminal font to "FragmentMono Nerd Font". Termina then shows the above error message. It actually can't find the "D2CodingLigature Nerd Font Mono" that I used and deleted. After that, no matter what fonts I select in Terminal's settings, it will report that it can't find "D2CodingLigature Nerd Font Mono".

Oh no. I hope this doesn't mean that your font cache is corrupted. 😣

Can you please try this series of steps? My hope is that this brings the cache back into a good state:

• Open %LOCALAPPDATA%\Microsoft\Windows\Fonts and check if the folder is empty. If it's not empty, open the Fonts control panel (search for "fonts" in the start menu):
  
  Find and delete each corresponding font until the %LOCALAPPDATA%\Microsoft\Windows\Fonts folder is empty.
• Download the D2CodingLigature font (https://github.com/ryanoasis/nerd-fonts/releases/download/v3.2.1/D2Coding.zip) again and install it for all users.
• Uninstall both, your "D2CodingLigature Nerd Font" and "FragmentMono Nerd Font" fonts simultaneously.

Afterwards, reboot your PC and try installing the "D2CodingLigature Nerd Font" (for all users).

I tried reinstalling "D2CodingLigature Nerd Font Mono" and it didn't pop up again, but I have a new problem: I can't select any font. It looks like some program is locking up my Terminal fonts!

[ShaneLee-9]

Oh, I seem to have found the reason. I don’t know when the font of Powershell was set separately in my terminal.

Thanks for following up!

[lhecker]

I'd like to apologize for not noticing the extra font face entry in your settings file. 😣
I'm glad however, that you were to able to resolve the issue!
