The following code, from the wiki, results in a compilation error: \starttext
\ctxlua{context(string.format("\%.2f", math.pi))} \stoptext
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, Antoine C. Full log: mtx-context | warning: synctex is enabled
