Subject: [NTG-context] Noto Emoji COLRv1
Date: Tue, 23 May 2023 15:31:48 -0600 [thread overview]
Message-ID: <62392038191a07c1e4a58ab90d3d104d91517bb8.camel@telus.net> (raw)
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] 🦆 % U+1F986
\stopTEXpage
but ConTeXt gives the following error:
fonts > otf loading > loading 'Noto-COLRv1.ttf', hash 'noto-colrv1'
otf reader > table version 1 of 'colr' is partially supported for font Noto-COLRv1.ttf
otf reader > unsupported colr type 2 paint format 0
otf reader > unsupported colr type 2 paint format %i
otf reader > fatal error in file 'Noto-COLRv1.ttf': ...ext/tex/texmf-context/tex/context/base/mkxl/font-dsp.lmt:3575: table index is nil

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).
Thanks,
