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)
