Given

"""
\newcommand{\oneEzeroC}{\protect{\transfont\string Ḍ\normalfont 
\selectfont}}
\catcode"1E0C=\active \def^^^^1e0c{{\protect\oneEzeroC}}

\newcommand{\forminindex}[1]{\catcode"1E0C=11\index{#1}\catcode"1E0C= 
\active}
"""

Calling \index{Ḍ}\forminindex{Ḍ} produces

"""
\indexentry{{\oneEzeroC }}{1}
\indexentry{{\oneEzeroC }}{1}
"""

What I have now gives acceptable results if I don't mind removing a  
few extra spaces in the .idx so that makeindex combines things  
correctly.
