[Tex/LaTex] \tau symbol like a real number \Re

Question

How can I get \tau to be like the real number symbol \Re similar to the ones in the attached photo.

Answer 1

Very ugly version with \bbtau from package mathbbol and its bbgreekl option. Don't use it ;-)

\documentclass{article}

\usepackage[bbgreekl]{mathbbol}


\begin{document}

$\bbtau$
\end{document}
