Hi @Finii, hadn't discussed this with you yet, but hoping you are open to adding Departure Mono! It's a new font, but given the rate of adoption we have seen since launch, I believe it is merited. I am already using a self-patched version in my terminal and editor, as are many others.

Let me know if there's anything else I can do to get this PR merged!

[m-ahdal]

This would be a wonderful addition. I personally know many programmers also manually patching the font (myself included)

[tmahmood]

Yes! Waiting for it to get merged.

[Finii]

Thank you 💚

Need to get the release out, started to work through the still open Issues and got sidetracked 😬

Hope they will not add 'special' weights, as ID1 is already on the length limit. Maybe switch already now to another naming mode 🤔 But then I see no Issue upstream no nothing, probably ok and the name is nicer how it is now.

Spot checked the GSUBs, seem all to be unproblematic

Preexisting boxdrawing glyphs will be replaced by full set from NF:

[rektdeckard]

Thanks for merging! Excited to use it officially :)

I do wish there was a way to keep our block elements and shading characters intact, as they're pretty unique to our font...but I understand that NF makes some promises there WRT consistent graphical characters.

[Finii]

Yes.

But the cell size might change on patching, so that the shading elements are not big enough anymore, or too big. I did not check.
The block drawing glyphs, well, they must fit in height/position and thickness to all the other ones that are missing, which seems to be ... unrealistic.

The patcher script checks if the complete set is existing, and if so the original glyphs are kept (and just rescaled to the new cell size, if the cell size changed). If one is missing all are replaced.

[Finii]

On the other hand, it is really easy for Helena to just add the missing glyphs. A partial set is not very useful anyhow.
