The following code, from the wiki, results in a compilation error:
\starttext \ctxlua{context(string.format("\%.2f", math.pi))} \stoptext
\startluacode ... \stopluacode but not in macros where the % is normally a comment again
The error is:
[\directlua]:1: invalid escape sequence near '\%' 1 \starttext 2 3 >> \ctxlua{context(string.format("\%.2f", math.pi))} 4 5 \stoptext
I ended using \letterpercent command but it is not very convenient.
Any help is welcome,
