Thanks for the pointer, Aditya.=C2=A0 I had not seen this,= but I couldn't get it to do what I wanted.

I don= 9;t fully understand what nofill does and how it interacts with fill and eo= fill.=C2=A0 I get strange results sometimes.=C2=A0 One complication, though= , is that the picture I get from lmt_outline seems to cover some part (smal= l 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 :=3D lmt_outline [
= =C2=A0 text =3D "=D8=B3=D9=84=D8=A7=D9=85",
=C2=A0 kind =3D &q= uot;fillup",
=C2=A0 align =3D "r2l",
] scaled 6mm;
= for i within op:
=C2=A0 nofill pathpart i;
endfor;
for i within op= :
eofill=C2=A0pathpart i withpen pencircle scaled 1mm;
endfor;
\st= opMPcode
\stoptext

Have you seen this example on the wiki which uses nofill:
