Found a workaround: The idea is to use \csname …\endcsname with two delimiters not likely to be used in math mode, below chosen to ‘…’. But then there seems to be a bug in the LuaTex \letcharcode command: There must be a character between “$” and the first occurring \activecatcode letter. Possibly this also causes a bug in \startformula, as discussed before. \setupbodyfont[xits,10pt] \setupmathematics[lcgreek=normal, default=normal] \def\usemathcommand#1’{\csname #1\endcsname} \appendtoks \catcode`‘=\activecatcode \letcharcode `‘ \usemathcommand \to \everymathematics \definemathcommand[𝐝𝐢𝐦][nolop]{\mfunction{𝐝𝐢𝐦}} \starttext Note that $ ‘𝐝𝐢𝐦’ 𝑉 = 𝖫$, although $\dim 𝑉 = 4$. And a bug: $‘𝐝𝐢𝐦’ 𝑉$. \stoptext
