And some proof assistant languages and frameworks. For a second I was really excited there, but this is another font with “programming ligatures”.
languages which insist on using full Unicode like APL and Agda have bigger problems (availability of uniform glyphs and inconsistency with monospace design) on their plates. which imo is one reason why full Unicode editing hasn't really caught up.
Myna doesn't use any ligatures though. it would run on almost all terminals and editors.
The big problem that I am having with this font is that its narrowness makes it difficult to find a fallback font for APL/BQN that plays well.
