oldstyle numerals in STIX Two Math

oldstyle numerals in STIX Two Math

[-- Attachment #1.1: Type: text/plain, Size: 504 bytes --]

I am trying to get the STIX Two fonts to display oldstyle numerals.

I have the oldstyle numerals in STIX Two Text, the problem is the math font.

So far, my mwe is:
\definefontfamily[mainface][rm][STIX Two Text][] %onum=yes does not seem to
work
\definefontfamily[mainface][mm][STIX Two Math][]
\definefontfeature[f:oldstyle][onum=yes]

\setupbodyfont[mainface, 18pt]
\addfeature{f:oldstyle}

\starttext
123456789
\blank[big]
$\sqrt{2} + 1234$
\stoptext

Any pointers will be greatly appreciated.

Alan

mtxrun --script fonts --list --info stixtwomath

shows that STIX Two Math doesn’t provide the onum feature.

Thanks, Hraban.That’s a helpful start

 I guess the challenge now is to get STIX Two Math to use the oldstyle
numerals in STIX Two Text (by adapting code that Wolgang gave me for using
 oldstyle numerals with TexGyre Math). When I ran

mtxrun --script fonts --list --info stixtwotext, I got

mtx-fonts       |   onum     cyrl     dflt

mtx-fonts       |            dflt     dflt

mtx-fonts       |            grek     dflt

mtx-fonts       |            latn     dflt rom trk

Sadly, I have no idea what this means or how it might help in identifying
the Unicode range of the oldstyle numerals in STIX Two Text. And that is
something I need to take advantage of Wolfgang’s code.

You replace the normal digits but apply the oldstyle feature.

\definefontfamily
   [alan] [rm] [STIX Two Text]
   [features={default,f:oldstyle}]

\definefallbackfamily
   [alan] [mm] [STIX Two Text]
   [range=digitsnormal,force=yes,features=f:oldstyle]

\definefontfamily
   [alan] [mm] [STIX Two Math]

\setupbodyfont [alan]

\starttext

abc 123456789 xyz

\m{abc\ 123456789\ xyz}

\stoptext
