This toki pona font is pretty mind-blowing https://github.com/janSame/linja-pona

Not only does it use ligatures to replace the ASCII characters with glyphs as you type, you can use a plus sign between them to combine glyphs. There's 120 words and the font accounts for over 6000 possible compound words

For example, if I wanted to write my surname, "bluelander", I could type "jan pi ma laso" and it converts it to the top four glyphs. But if I want to make a signature for myself, I type jan pi+ma+laso [_ma_akesi_e]
The first part means "person of the blue land" and the part in the cartouche is "ma akesi e", a phonetic representation of "matt" in the toki pona syllabary (mae pronounced as two syllables, like "mah-eh"). So cool!
