 Dear Hans,
 Hello

 With the above code the digits are not changed to persian. For your
information I have
 attached the source, log, and PDF files.

 Please note that I have changed '\setupbodyfont[dejavu] to
\setupbodyfont[dejavusans]
 because the font 'dejavu' is not installed on my system.

 Thanks,
 Mingranina
