            Bug ID: 105492
           Summary: fontconfig-2.13.0 globally sets the locale from the
                    environment
           Product: fontconfig
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: library
          Assignee: fontconfig-bugs at lists.freedesktop.org
          Reporter: ulm at gentoo.org
        QA Contact: freedesktop at behdad.org

Function FcConfigEnsure globally sets the locale by doing:
        setlocale (LC_ALL, "");

This countermands any locale settings in the calling program. For example, GNU
Emacs sets LC_NUMERIC to "C" which is undone by the fontconfig library. In
turn, this breaks Emacs' lisp reader.
