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) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
