Hi,
I noticed that in the latest LMTX version, ^^ (with ^ of catcode 7)
is no longer interpreted inside csnames. Is this intentional?
(Example:
\starttext
\catcode\circumflexasciicode=\superscriptcatcode% Ensure correct catcodes
\show ^^41 % This still works and shows "> the letter A"
\show^^41 % This used to be an error "Undefined control sequence \showA",
% now show "> The letter A"
\show\^^41 % Used to show "> \A=undefined", now shows ">
\^=macro:->\enco_handle_accent {^}"
% and "! Missing $ inserted"
\stoptext
)
Indeed that is intentional because in lmtx we disable them (partially).
You have to say:
\normalsupmarkmode\zerocount % we use 1 as default in lmtx
This is because in lmtx we have native prescript support, as in:
$ x^{rt}_{rb}^^{lt}__{lb} $
so, double _ ^ can have a different meaning there.
