Change some Latin characters. Opinion?

Open kiwi0fruit opened this issue 6 years ago • 14 comments

I'd like to change some Latin characters. * Adapt <>, ≤≥ from Crimson (Check other symbols like <>), * Change italic g to the one like in Computer modern (single-story): make g from a and ɡ. Bold and semibold make from a and 5 (also check ʒ). I think single-story g is better for mathematical contexts. It would look like the 1st one:

What do you think about it? Would you merge it?

As a publishing house with print works released in both Libertinus Serif and Crimson Text, I would not be too keen on a switch to a singe story g. In fact I would actively vote against that. If a a single story version is better for math contexts that could be done in Libertinus Math, but please don't touch Libertinus Serif. I also think the respective numbers are a better match for their respective fonts as they are now. I don't see any reason to swap them out. I just had a look at @ and like the Crimson one but don't see a need to change the Libertinus one either.

Left: Libertinus Serif, Right: Crimson

Actually numbers are the last in line :) Just thoughts...

@ is rather easy to change

The single story g is the main interest.

We already have a single storey g glyph for ɡ that is used in IPA, if math users really prefer a single storey math g, we can switch to that glyph. Though I checked both STIX and STIX Two math fonts and they use double storey italic g (STIX Two uses a single storey one for the bold italic, though), so that does not seem like a universal preference, so I’d add the single storey g as an alternate.

For the other suggestions I agree with what @alerque said.

It's not g actually in the IPA - see the right glyph in the top post picture - that's it. The proper italic g should look like the left glyph on that pic.

And I it's better to look at Cambria Math and Computer Modern - I think they are more popular than STIX. They both have single story italic g.

Both Cambria Math and Computer Modern are in style too far away from Libertinus, however STIX is far closer to it so it is an appropriate comparison IMO. I don’t have a string objection about you proposed g, but I don’t want it to be the default.

I think they are closer to Libertinus than to each other. But both have single story g. It's not about font style. It's about when you write g(x) on paper it's always single story. And math font inherits this.

But still Libertinus Serif is a transitional font. And most of the transitional fonts have double story g (except Georgia and some other)...

Single/double story aside: I think that italic g from Libertinus Serif is too similar to regular. For comparison here are some screenshots from nice math font review: (first one is Libertinus, others - clearer italic g that can't be confused with regular one)

@khaledhosny Would you pull it if I implement it as a stilistic set: https://helpx.adobe.com/typekit/using/open-type-syntax.html#ss## ?

Yes.

I agree, having a single-story g as a stylistic alternate in Libertinus Math would be great! For the record, this is exactly what STIX 2.0 does as well, here's an excerpt from their documentation: screenshot at 2018-04-22 19-21-23

Can't wait to see it. The :+1: was meant for Libertinus Math. Question aside: Is there a v in Libertinus Math like STIX default?

Bolpat avatar Apr 26 '18 20:04 Bolpat

I think the question is already answered; a pull request to add an optional alternate italic g for math is welcomed.
