Hi, Wolfgang—

The mwe is:

\definefontfamily[mainface][rm][STIX Two Text]

[protrusion=quality,

expansion=quality, 

mode=node,

force=yes,

features={default, f:oldstyle},

]

]

\definefallbackfamily[mainface] [mm] [STIX Two Text]

  [range=digitsnormal,

force=yes,

features=f:oldstyle]

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

\setupbodyfont[mainface, 20pt]

\starttext

Hello world!

123456789

\m{123456789}

\oldstyle{123456789}

\stoptext

The problem disappears if I remove either

\definefallbackfamily[mainface] [mm] [STIX Two Text]

  [range=digitsnormal,

force=yes,

features=f:oldstyle]

or

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

But in neither case do I get oldstyle numerals.

Note too that, when I remove \definefontfamily[mainface][mm][STIX Two Math], my log file has 

mkiv lua stats  > loaded fonts: 2 files: lmmono10-regular.otf, lmroman10-regular.otf

with no mention of STIX Two Text.

Yet ConTeXt is aware of the STIX Two Math and STIX Two Text fonts.

WE had a power failure very recently. I wonder if that has screwed things up.

Hi, Wolfgang—

I copied all the fonts to a new document (file attached) and ran ConTeXt. The problem persists. The cause, I think, comes in the lines:

\definefallbackfamily[mainface] [mm] [STIX Two Text]

  [range=digitsnormal,

force=yes,

features=f:oldstyle]

which used to give me oldstyle numerals.

I'm unable to reproduce the error with your example and most of the fallbacks are ignored because I don't have the fonts.

To ensure there is no problem with the format and font database delete the cache and rebuild it:

        mtxrun --script cache --erase
        mtxrun --generate

When this doesn't help you simplify your example. First remove one \definefallbackfamily at a time and afterwards remove \definefontfamily until the error disappears.

Wolfgang
