def get_fontconfig_pattern(self):
return generate_fontconfig_pattern(self)<EOL>
Get a fontconfig pattern suitable for looking up the font as
specified with fontconfig's ``fc-match`` utility.

See the documentation on `fontconfig patterns
<http://www.fontconfig.org/fontconfig-user.html>`_.

This support does not require fontconfig to be installed or
support for it to be enabled.  We are merely borrowing its
pattern syntax for use here.
