How to get j where the dot in the j becomes a tilde?

Question

How do I get a j in math mode, where the dot in the j becomes a tilde? Attached is a picture.

Thanks!

Answer 1

Use \tilde{\jmath}, but one may argue that the j character is not really nice then.

\documentclass{article}

\begin{document}
$\tilde{\jmath}$
\end{document}
