Dear All, Hello,

I am trying to use Persian digits in math formulas. My document reads:

\font\4 = {name:dejavusans} at 10pt

\font\5 = {name:dejavusans} at 7pt

\font\6 = {name:dejavusans} at 5pt

\textfont4=\4 \scriptfont4=\5 \scriptscriptfont4=\6

\Umathcode`3="1"4`۳

\definefontfeature [persian] [arabic]

\mainlanguage[pe]

\starttext

\definedfont[dejavusans*persian]

\setupalign[r2l]

این یک آزمایش است.

3+2=5

$3+2=5$

\setupalign[l2r]

This is a test.

3+2=5

$3+2=5$

\stoptext

However in the output the replaced digit "3" disappears. Any help is gratefully appreciated.

For a text font you can add:

\definefontfeature [persian-fake-math] [arabic] [anum=yes]

and say:

\definedfont[dejavusans*persian-fake-math]

but ... nicer is this:

\mainlanguage[pe]

\usetypescriptfile[dejavu]

\definetypeface [dejavu] [rm] [serif] [dejavu] [default] \definetypeface [dejavu] [ss] [sans] [dejavu] [default] \definetypeface [dejavu] [tt] [mono] [dejavu] [default] \definetypeface [dejavu] [mm] [math] [xitsbidi] [default] [direction=both,rscale=1.2]

\setuptypeface[dejavu]

\starttext

\start \setupalign[r2l] \setupmathematics[align=r2l] arabic: این یک آزمایش است. \par text: 3+2=5 \par math: $3+2=5$ $\sqrt{3+2=5}$ \par \stop

\start \setupalign[l2r] \setupmathematics[align=l2r] latin: This is a test. \par text: 3+2=5 \par math: $3+2=5$ $\sqrt{3+2=5}$\par \stop

\stoptext

(see bidi-001.tex in the test suite)

Dear Hans, Hello Thank you very much for your reply. 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. By the way, I couldn't find "bidi-001.tex" on ConTeXt Site, would you please let me know where can I get it? Thanks, Mingranina The problem wi

The file is part of Hans test suite you can find on his homepage: - http://pragma-ade.com/download-1.htm - http://pragma-ade.com/context/latest/cont-tst.7z Wolfgang

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

Dear Wolfgang Schuster, Hello The above code works on my system too, but in text mode the digits are still in English.

The DejaVu fonts are shipped with your context installation and you can use them with \setupbodyfont[dejavu], when you write \setupbodyfont[dejavusans] context uses Latin Modern because there is no typeface with the name “dejavusans”.

Do you know in which files are these typefaces defined? I want to use them as sample files and define my own typefaces (if I can at all). Thanks Migranina
