Choosing STIX stylistic sets

Choosing STIX stylistic sets

[Hans Åberg]

With the STIX Two fonts [1-2], one can choose say Stylistic Set 8 <ss08> for more upright integrals. How is that done in ConTeXt with XITS?

On MacOS, it does not load the fonts: In the example below (also not working with 'xits' or 'stix'), I get:
fonts           > typescripts > unknown library 'stix-two-math'
fonts           > preloading latin modern fonts (third stage)
fonts           > 'fallback modern-designsize rm 10pt' is loaded

They are installed as system fonts.

Also, though \iiiint now seems defined, the limits are still underneath with the option 'integral=nolimits'.

This is complicated, it seems: The STIX2Math font does not have the text support that STIX has, so one might want a virtual font, or set the math font independently (I could find any info about that on ConTeXtGarden).

Also, in script/calligraphic, STIX2 seems to have is the other way around relative stix-two-math.lfg: setting the feature 'ss01' yields the traditional English script style, whereas the default is the AMS calligraphic style.

On most other features, the STIX2 default seems to what I think of as traditional.

The feature 'ss07', smaller operators, might be nice to have, but U2205 looks strange, as the empty set symbol comes from a Danish ø, so deselecting just that one might be of interest.

there is no real text support in math fonts ... it's alphabets ... the 
fact that one shares e.g. a textfont in math mode with a regular text 
font outside math is something traditional tex (and more a font design 
and macro package issue that an engine thing)

just use a text font .. why does texinfo needs a math font? only for 
math i assume

> Also, in script/calligraphic, STIX2 seems to have is the other way around relative stix-two-math.lfg: setting the feature 'ss01' yields the traditional English script style, whereas the default is the AMS calligraphic style.

that's also a design issue

personally i'd never use stix for something (one can use texgyre pagella 
or termes)

one more reason for not using stix

So far I have only used \setupbodyfont[xits,10pt], but found no info about how to specifically selecting fonts for the different modes or ranges.

> just use a text font .. why does texinfo needs a math font? only for math i assume

Right, and writing the Unicode math characters in the UTF-8 source file, in part because they will be also used as such in the source code of a program. One can otherwise embed formulas using traditional TeX syntax.

Not anymore, perhaps, as some mathematicians seem to think of them as different semantic styles.

I used STIX because it came around, and, also, the AMS has been involved. It good there are other fonts, though.

What is the advantage of those?

\setupbodyfont[termes]
\setupbodyfont[pagella]
\setupbodyfont[bonum]

on windows (cambria is the opentype reference fonmt for math):

\setupbodyfont[cambria]

or when you bought lucida ot:

\setupbodyfont[lucidaot]

all have math

it's a bit more complex in the tex world: users are accustomed to seeing 
the a in $a$ becoming a math italic a and $\bf a$ getting a bold a .. 
both are in the unicode math alphabet so a macro package has to support 
both these switch driven inputs and direct unicode math (also because 
cut and paste from a pdf should work)

(the way macro packages implement that can be fundamental different)

(there is a font project under way that will provide monospaced math 
characters for editing)

if so, then that will be reflected in unicode alphabets (just make a 
string case for it)

finally came around .. but it's not a pretty font

a palatino based font looks imo better than stix

(as open type font they are around a bit longer and we have a bit more 
influence on their development)

But that sets it for all, text and math, right?

We discussed that by option \setupmathematics[lcgreek=normal, default=normal], which makes sure math characters are untranslated. I have used that for some time now, and that works fine.

We discussed that, too. ASCII computer code that has been written in monospace using space to produce column looks weird in a variable width font, but otherwise, it is just a style.

It has been discussed on the Unicode list. Personally, I think the calligraphic style looks wrong. The script style is essentially an English handwritten style, also used in Sweden.

The last has weird design of, for example, 𝜑 and ∑, and is a bit too heavy in my taste.

In these two examples, of the same author, but different publishers, the integral signs are heavier in the middle, which looks nice. The second has nolimits, but not the first.
