Thanks.  This resolved the problem.  I now get that ligature.  The 
problem for me now is how to get the hyphenation working.  I don't 
recall whether it was working before making this change, but it 
certainly is not now.

Here is what I have in the preamble:

\usepackage{polyglossia}

\usepackage{fontspec,xltxtra,xunicode}

\setmainfont[]{Gentium Basic}

\setdefaultlanguage{english}

\setotherlanguage{sanskrit}

\newfontfamily\sanskritfont{Nakula}

\newcommand\dn{\catcode `\~=12

\fontspec[Script=Devanagari,Mapping=velthuis-sanskrit]{Nakula}}


I am using TeXworks to generate the pdf.

Using these settings I get the following error message:

"("C:\Program Files\MiKTeX 2.8\tex\xelatex\polyglossia\gloss-sanskrit.ldf"

Package polyglossia Warning: No hyphenation patterns were loaded for 
`Sanskrit'

(polyglossia) I will use the patterns loaded for \language=0

(polyglossia) instead on input line 6."


Where am I going astray?

Any suggestions for a devanagari input method that might be better 
(easier) than using the velthuis system?  I am working in Vista and with 
MiKTeX. 

Thanks.
