Oh! That is very clever. Thank you.

Both! Unicode has some support for as-is ligatures. For example fi is U+FB01.

Modern fonts can also use self-defined ligatures. That’s how fonts like https://www.sansbullshitsans.com/

So my plan is (eventually) to add in ligatures where Unicode has defined them - and automatically replace typed text with self-defined ligatures where it doesn’t.

Cheers. The code was cobbled together by me from various random tutorials and things I had laying around.

Thanks :-) It was a couple of days work. Mostly teaching myself stuff that I’d forgotten. I blogged about it so others can follow the process if they want.

We’re getting a bigger solar battery installed next week! So lots of tidying up the porch, making sure we have tea and biscuits on hand, and researching whether we can move to a dynamic electricity tariff.

And hoping next week is sunnier so we can fill the damned thing!
