Subsetting Historic Ligatures #295

Open bryankaplan opened 3 weeks ago

bryankaplan commented 3 weeks ago

Is it possible to specify a subset of hlig? If so, how?

psb1558 commented 3 weeks ago

Are you using pyftsubset from fontTools? I ask because this is the only tool I've made much use of, and it allows fine control of your subsetting.

bryankaplan commented 3 weeks ago

pyftsubset looks quite useful, and it may well answer this question. I don't know yet.

But I may have chosen the wrong word when I said “subset”. Provided a non-subsetted junicode font, is it possible to indicate some (and only some) of the sub-features of hlig?

psb1558 commented 3 weeks ago

Ah. I see. Sorry, but I don't know of any way to make hist work that way. The feature has just got to be on when you want it and off when you don't. I don't need it myself, but I can see that it could be a pain to use.

psb1558 commented 3 weeks ago

I have been thinking, actually, of offering an alternative way of getting these ligatures: by placing U+200D zero width joiner between two characters. Then the three-character sequence could be resolved in liga Standard Ligatures instead of in hist. This might make it easier to get individual ligatures without having to turn a feature on and off, possibly disrupting kerning and contextual alternates.

The ZWJ idea is smart, and I'm sure if you add it, some people will use it.

That being said, for covering an entire text it's generally easier to enable a feature. I just wish they could be enabled individually.

psb1558 commented 3 weeks ago

Yeah, it would be nice. I've just reviewed the OpenType GSUB lookup types again, and I can't see a way to make it work. If anyone passing by here has an idea, I'd love to hear it.

If you can use LuaLaTeX for your document, selnolig readily covers this problem with the \nolig macro.
