Hi Hans,
In case you missed it, Max Chernoff has a patch for ConTeXt below.
i don't track SE to i missed it and if you have such issues best take it
to the mailing list
I'm about to release a new version of KeenWrite that has scores of
fixes. I'd like to upgrade the container with a version of ConTeXt that
has the fix in place. I could patch the container, but would prefer
pulling from official sources.
Thank you!
Cheers!
Dave

although it fixes the issue it's not the reason; as we want roundtrip

the exception option in the above deals with it
in cldf-ini we need to change this

i'll ponder the catcode change but wonder if it will have other side

See https://tex.stackexchange.com/q/750584/2148 <https://

that's not the best place to discuss / fix this
