Human-readable ligatures?

Feature request

I'd like to be able to use a word as a ligature in a font, but for some reason it doesn't seem to work. For example, unicode: ['heart'] would ideally only render a heart icon when the user types 'heart'.

For some reason this doesn't currently work.

What's weird is that if you change the code to not HTML-escape ASCII characters in the unicode parameter, the conversion to TTF still doesn't seem to work. It ends up not rendering anything for any of the letters in heart at all, just blank. Instead of the normal rendering of a black box for unknown glyphs.
