I would be happy to improve the support for XeTeX in grffile.
However, I do not know any other driver than pdfTeX (or LuaTeX)
that provide a safe file existence check. In case of pdfTeX
package grffile uses \pdffilesize, the file name argument
is <general text> as \pdfximage uses.

Some TeX ports support double quotes, but

  in file names, although most file systems and OPs allow them.

However it would be nice, if the file name problem could
be solved in a clean way.
