PS:
WIth LuaLatex you handle alt_title also by
#+begin_src org
* \(\textbackslash{}đ\) wraps
:PROPERTIES:
:ALT_TITLE: \(\textbackslash{}Ï\) wraps too
:END:
#+end_src
So there we don't need the \texorpdfstring{}{} as long as we translate the
backslash as
\textbackslash{} and not as $\backslash$
I did it again (oops) ;-)
