I've been using Go/Go Mono as system fonts for a while, and they're one of my favorite typefaces. Their spiritual predecessors, Luxi Sans/Serif/Mono, are also worth checking out.

Go Mono is my favorite console font, alternating with Plex Mono...

I have been using that font as my main development font since it was released. Great looking font. Although I have to give an accolade to Iosevka which is easily my favourite "narrow" font.

I switched to this right after it came out - it's amazing.

Unfortunately it isn't using a usual font license. It's not really clear under what conditions you can use/redistribute it.

According to the GP's site:

> They are licensed under the same open source license as the rest of the Go project's software

Which I assume is this one: https://golang.org/LICENSE

It may not be usual, but what about the licensing terms is unclear?

It’s unclear whether I need to include a copyright for this font in every PDF I create that uses this font. SIL Open Font License explicitly doesn’t apply to documents using this font.
