I've been working on revisions to seven ETC typefaces for almost eight months now. Before that, I had high hopes for a little project called Public Type Works (PTW - currently hibernating) which was an attempt to crowdfund open source fonts. It was a nice idea, and everything "worked" properly, but it failed. The numbers just didn't meet our goals.
Sono was one of my two "in-progress" typefaces I was trying to fund via PTW. It wasn't finished back then but that was the point of the website, to get people to chip in enough money so that type designers can sustainably make open source fonts. But last week I finally got Sono to a good enough state to be able to share it on Github. It's a soft monospace, which is why I call it Sono (rhymes with mono). It's variable but also available in seven static weights from extralight to extrabold.
Sono has a pretty low cap height, which I like. I think it works well for ALL CAPS, especially since it is monospaced. I'll probably let it sit for a bit before working on it again. You can download it easily from the Sono releases page. Wakamai Fondue says Sono supports the following languages: Afrikaans, Albanian, Basque, Bosnian, Catalan, Croatian, Czech, Danish, Dutch, English, Estonian, Faroese, Filipino, Finnish, French, Galician, German, Hungarian, Icelandic, Indonesian, Irish, Italian, Latvian, Lithuanian, Malay, Norwegian Bokmål, Polish, Portuguese, Romanian, Slovak, Slovenian, Spanish, Swahili, Swedish, Turkish, Vietnamese, Welsh, Zulu
