Hi Hans,
I tried using the code from [1] for Noto Emoji in COLRv1 format [2]:
\startTEXpage
\definefontfeature[colored][default][colr=9]
\definedfont[Noto-COLRv1.ttf*colored] 閭 % U+1F986
\stopTEXpage
but ConTeXt gives the following error:

with id 1: missing
From what I can tell, the Lua code is trying to read past the end of
font file. I tried debugging the error further, but this is well beyond
my understanding.
(Also, paintreaders[6--11] in font-dsp.lmt are missing "offset" in the
function signature, and paintreaders itself is glboal. Maybe related?)
I'm using the current latest (2023.05.08 17:39).
i'll check it but as usuel with these new things in fonts, one depends
on fonts for testing so all that goes stepwise (as - hopefully correct -
fonts come available)
