I have a little problem with a ligature, if that's the proper term, while composing in Devanagari via xeLaTeX. I remember someone mentioning there was a newsgroup devoted exclusively to Devanagari composition questions, but I have not been successful in finding it. Can anyone direct me?

Gratefully,
Bob Hueckstedt

PS: If you're interested, the problem has to do with j~na. It comes out fine in regular text, but it does not come out fine in footnotes.

Here's a sample file:

\documentclass{article}
\usepackage{fontspec}
\usepackage{xunicode}
\usepackage{xltxtra}
\setmainfont{IndUni-P}

\newcommand\dn{\catcode`\~=12
   \fontspec[Script=Devanagari,Mapping=velthuis-sanskrit]{Sanskrit2003}}

\begin{document}
{\dn j~nAna}\footnote{The meaning of this is {\dn j~nAna}.} {\dn vidyA}
\end{document}
