\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.

@ChristianHupfer I have removed that tag (and formatted a bit). OOzyPal Do you mean this blackboard math font? — TeXnician, Jun 2, 2017 at 14:54
@TeXnician: I could have removed the tag also, but I wanted to 'annoy' the O.P. ;-) — user31729, Jun 2, 2017 at 14:55
Your Title is very confusing as you show blackboard bold (double struck) R but you ask for a style like \Re which makes a script R not at all like the image that you show. — David Carlisle, Jun 2, 2017 at 15:05

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}

interestingly enough Unicode only has the math double struck in latin and arabic, not greek..... So if this was used in publication once could apply to extend Unicode...

As you said it is ugly :). Also it does not scale well with the other equations. I will just go with \mathbb{T}.

@OOzyPal: Well, you asked for \tau in black board letters. \mathbb{T} is black board T ;-)
