Hi,
shouldn't \supmarkmode=1 only disable these in math mode?
In any case, \normalsupmarkmode\zerocount doesn't make a difference
here:
\starttext
\normalsupmarkmode\zerocount
\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
shows exactly the same behavior.
