[libxml++] Stop exceptions when using std::cout and UTF-8.

[Murray Cumming <murrayc src gnome org>]

commit 6f91e4489fba79f70c33029d2d9a76fd03fe6276
Author: Murray Cumming <murrayc murrayc com>
Date:   Tue Mar 30 18:06:26 2010 +0200

    Stop exceptions when using std::cout and UTF-8.
    
    * examples/*/main.cc: Initialize the global C and C++ locale to prevent
        exceptions when ouputing a ustring (with non-ASCII UTF-8) to std::cout.
        We don't see this problem when writing gtkmm apps because gtk_init() (via
        Gtk::Main) initializes the C locale correctly.
    
        Thanks to Daniel Elstner for the solution (he will document it properly
        in the Glib::ustring API reference) and to Nic Reveles and others for
        noticing the problem.
