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.
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!
Done! Thanks :-)
