I cannot get Emacs on Windows to display _any_ non-ASCII text with the
above recipe, not even if I use Latin-1 characters or characters from
the current system codepage.  Emacs encodes non-ASCII characters as
&#nnnn numbers (you can see that if you type "C-c C-c" in the
*svg-test* buffer), which is probably correct, but the SVG image is
not displayed for some reason.

Alan, any ideas or suggestions?
