Currently luamplib does not provide any helper function for
'runscript', but we can do it anyway. For instance:
---------------------------
\documentclass{article}
\usepackage{luamplib}
\begin{document}
\mplibtextextlabel{true}
\begin{mplibcode}
beginfig(1);
string Test;
Test="AaeéB";
for k=1 upto runscript("return utf8.len[["&Test&"]]"):
label.top(runscript("local t=[["&Test&"]];local k="&decimal
k&";return
string.format('%q',utf8.char(utf8.codepoint(t,utf8.offset(t,k))))"),(k*1cm,0));
endfor;
endfig;
\end{mplibcode}
\end{document}
