I want to have a mirror image of a diacritic mark of Devanagari script.

```
\documentclass[varwidth,border=0.2cm]{standalone}
\usepackage{graphicx}
\usepackage{fontspec}
\setmainfont[Script=Devanagari]{Shobhika}

\begin{document}
    म्\par
    म\reflectbox{्}\par
    म\scalebox{-1}[1]{्}
\end{document}
```

Though Unicode's mechanism won't allow this, I wanted to know if there is a way to do this in TeX. If not I'll do it with Ti*k*z.
