Hi, I'm trying to get tikz-cd to run on LMTX and some examples already work fine, but I had a problem with text on arrows.
To reproduce: \usemodule[tikz] \usetikzlibrary[cd] \starttext \starttikzcd A \arrow{r}{A} \NC B \NR \stoptikzcd \stoptext This builds fine on MkIV from TeXLive 2022 with LuaTeX, but on LMTX I get: system > ConTeXt ver: 2022.09.11 20:44 LMTX fmt: 2022.9.20 int: english/english ... close source > level 2, order 63, name 'tikzlibrarycd.code.tex' fonts > preloading latin modern fonts (second stage) fonts > 'fallback modern-designsize rm 12pt' is loaded tex error > tex error on line 8 in file ./tik.tex: Package pgfkeys Error: I do not know the key '/tikz/"{A}"{}' and I am going to ignore it. Perhaps you misspelled it.^^J...^^Jl.7 I think the culprit is a tikzcd arrow in cell 1-1 After a bunch of debugging, it turns out that LMTX breaks the TikZ 'quotes' library, which works using code ala: \def\tikz@enable@node@quotes{% \pgfkeyssetvalue{/handlers/first char syntax/the character "}{\tikz@quote@parser}% \let\tikz@quotes@as\tikz@node@quotes@as% } The last part of the /-key is derived from \meaning, but in LMTX, \meaning" is "the character U+0022 'quotation mark'" and thus the key cannot be found. I have patched TikZ for now to match for this alternate string too. But perhaps it would be better for compatibility to agree with the original TeX \meaning strings for the 7-bit ASCII subset at least. I found another minor nit that's not really triggering a bug but still a difference to LuaTeX: \eTeXrevision should expand to .2, but it expands to 2 in MkIX. There is some code out there which uses constructions like \number\eTeXversion\eTeXrevision or even \ifdim 0\XeTeXrevision pt > 0.9996pt As LMTX doesn't care about this macro, this should be easy to adjust.
