Thanks for the pointer, Aditya. I had not seen this, but I couldn't get it
to do what I wanted.
I don't fully understand what nofill does and how it interacts with fill
and eofill. I get strange results sometimes. One complication, though, is
that the picture I get from lmt_outline seems to cover some part (small
area around the joining part) twice, so that messes up the even/odd logic
of eofill.
Here is one of the things I tried:
\starttext
\definedfont[dejavusansmono*arabic]
\setupalign[r2l]
\startMPcode
picture op; op := lmt_outline [
text = "سلام",
kind = "fillup",
align = "r2l",
] scaled 6mm;
for i within op:
nofill pathpart i;
endfor;
for i within op:
eofill pathpart i withpen pencircle scaled 1mm;
endfor;
\stopMPcode
\stoptext
