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. bowen1@acbs-mbp ~ % mtxrun --script fonts --list --all stixtwotext yields identifier familyname fontname filename subfont instances stixtwotext stixtwotext stixtwotext /Users/bowen1/Library/Fonts/STIX2Text-Regular.otf stixtwotextnormal stixtwotext stixtwotextitalic STIXTwoText-Italic.otf stixtwotextregular stixtwotext stixtwotextmedium STIXTwoText-Medium.otf On Thu, Apr 29, 2021 at 2:25 PM Wolfgang Schuster < wolfgang.schuster.lists@gmail.com> wrote:

With ConTeXt ver: 2021.04.28 18:39 LMTX fmt: 2021.4.29 int, I am now getting the following error on compiling with files that were OK previously. Is there something that I need to change?

The error is caused by the fallback font for math but you have create a minimal example because I'm unable to reproduce it (copy all font settings to a new document and run ConTeXt).

Can you also check if the font files are found by ConTeXt:

mtxrun --script fonts --list --all stixtwotext*

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.

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.
