[XeTeX] Trouble with displaying word containing 3 conjunct consonants in Devanagari

[Guido Herzog]

Test  the following code

%!TEX TS-program =  xetex
%!TEX encoding   =  UTF-8 Unicode

% glyphlist.tex -- to find glyphs and their index

\parindent 0pt

 \font\test="Chandas"    at 14pt
%\font\test="Charis SIL" at 14pt

\newcount\charcountA \charcountA 0

\newcount\charcountB \charcountB \XeTeXcountglyphs\test \advance\charcountB -1
\newcount\charcountC \charcountC 0

\def\ystrut {\vrule height 15.0pt depth 5.5pt width 0pt}

\advance\vsize 4\baselineskip

\loop
 \advance\charcountC 1
 \leavevmode
 \hbox{\hbox to 10mm{\hss\number\charcountA\quad}%
       \hbox to 10mm{\test\XeTeXglyph\charcountA\ystrut\hss}%
      }%
 \ifnum\charcountC = 8 \endgraf          \charcountC 0 \fi
 \ifnum\charcountA < \charcountB \advance\charcountA 1
\repeat

\bye
