Question

How can I write letter d with hyphen in the image file?

Answer 1

If you need it in the smaller math styles, let me know. This only works in display/text-styles.

\documentclass{article}
\usepackage{stackengine}
\newcommand\stroked{\ensurestackMath{\stackengine
  {3.2pt}{d}{\mkern5.4mu\mbox{-}}{O}{l}{F}{F}{L}}}
\begin{document}
\stroked
\end{document}
