If I have this  in an org-file, I was surprised to see different behavior of the export depending on the value of org-html-with-latex. Unless I set it to dvisgm, then the backslashed path seems to get removed. Is this as surprising as it seems to be?

*%appdata%\Path\Path\Path*

* Code                                                             :noexport:

#+BEGIN_SRC emacs-lisp

(let ((org-html-with-latex 'dvipng))

  (with-current-buffer (org-export-to-buffer 'html "*Formatted Copy*" nil nil t t)

    (buffer-string)))

#+END_SRC

#+RESULTS:

: <p>

: <b>%appdata%</b>

: </p>

#+BEGIN_SRC emacs-lisp

(let ((org-html-with-latex 'dvisgm))

  (with-current-buffer (org-export-to-buffer 'html "*Formatted Copy*" nil nil t t)

    (buffer-string)))

#+END_SRC

#+RESULTS:

: <p>

: <b>%appdata%\Path\Path\Path</b>

: </p>
