Font rendering issues in Terminal

[mqudsi]

I have Terminal up and running under 18362.0, but it seems to have problems with certain types of fonts.

Here it is working fine with the font set to "SF Console":

But it breaks when the font is changed to "SF Console Medium" (but not because the font isn't found or anything). The app doesn't crash but the text is rendered... let's just say extremely incorrectly:

If you focus extremely well and zoom in all the way, you can see that text is being rendered.. just very oddly so. Change the font back and it redraws correctly to what it used to contain.

Here's the same screenshot from conhost with the font set to "SF Console Medium" via the registry:

It's not just an issue with setting a variant of a font, or this particular font. Here's how the default (free) "Roboto Slab" is rendered, but I'm not sure if it's the same problem (it doesn't look like it):

@miniksa is the guy who will know why this is happening.

Is "SF" the San Francisco font from Apple that we're absolutely not authorized nor licensed to use outside of an Apple computer?

If so, I can't investigate this and have to slam it closed. I can't debug/diagnose fonts I'm not licensed to use and I can't condone having other people break that license agreement.

No, that is SF Mono. SF Console is a clone intended to look like it but not one I'm authorized to share; which is why I mention Roboto Slab, which is open source and publicly available.

Where can I get it and confirm the licensing?

It's made by Google, released under the Apache 2.0 license. GitHub repo: https://github.com/googlefonts/robotoslab

You can download the prebuilt TrueType files here: https://github.com/google/fonts/tree/master/apache/robotoslab

OK thanks. I'll take a look at it then when I get around to being able to work on rendering stuff instead of triaging GitHub issues and PRs all day. :P
