A math formula In Persian language is exactly the same as in English
language except that the
  digits should be written in Persian. So what I want to do is to
replace the English digits with
  Persian digits in a math formula. However, with your code not only
the formula is right aligned, but
  also the square root symbol is mirrored.
Assuming that you use math consistently ...
\starttypescript [mathdigits] [all]

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
