+.. function:: escape(pathname)
+
+   Escape all special characters (``'?'``, ``'*'`` and ``'['``).
+   This is useful if you want to match an arbitrary literal string that may
+   have special characters in it.  Special characters in drive/UNC

 :file:`1.gif`, :file:`2.txt`, and :file:`card.gif`.  :func:`glob` will produce
 the following results.  Notice how any leading components of the path are
