[Tex/LaTex] How to type special character– a Y with a line through it

Question

The symbol I'm looking for is similar to the one produced by \mathfrak{X}, but with a Y instead of an X. I've spent hours looking for this, combed through every character list I can find, tried detexify, and I can't find the answer anywhere. If this question has been asked before, I apologize, please direct me to it, I've looked and haven't found it. Thanks!

Answer 1

Since it is not exactly clear if you want a normal "Y" or a fraktur "Y", I provide both... (note that these are designed to take up the same space as an unadulterated "Y" or \mathfrak{Y})

The stoke elevation can be adjusted with the first argument of \stackengine.

\documentclass{article}
\usepackage{amssymb}
\usepackage{stackengine}
\def\strokeY{\ensurestackMath{\stackengine{0pt}{-\,}{Y}{O}{c}{F}{T}{L}}}
\def\strokefracY{\ensurestackMath{\stackengine{0pt}{\,-}{\mathfrak{Y}}{O}{c}{F}{T}{L}}}
\begin{document}
$\strokeY =  X$

$\strokefracY =  X$
\end{document}
