Bonjour,

Using the velthuis tranliteration scheme to type devanagari texts, I recently came accross some problem with ~n to produce ञ glyph.

In tabular like environment, the ~ returns to its non -break space status and ~n is rendered as न

Here is a MWE:
<----------------------------------------
\documentclass[a4paper,twoside,11pt]{report}

\usepackage{fontspec}

\setmainfont{FreeSerif}[%
Script=Default,%
Mapping=tex-text,%
Fractions=On,%
Numbers=OldStyle,%
]

\newfontfamily{\sanskritdev}{%
  FreeSerif}

\newenvironment{deva}{%
  \catcode`\~=12%
  \sanskritdev%
  \addfontfeature{%
    Mapping=velthuis-sanskrit,%
    Scale=MatchLowercase,
  }%
}%
{\catcode`\~=13}

\usepackage{stackengine}

\begin{document}

\newcommand{\vaq}[2]{%
  \begin{tabular}{@{\,}c@{\,}}
    #1\\
    {\deva #2}
  \end{tabular}%
}

\newcommand{\vak}[2]{%
  \stackon{#1}{\deva #2}%
}

{\deva ~na}

\vaq{2}{~na}

 \vak{3}{~na}

\end{document}
<-------------------------------------------
