Thu Nov  6 00:04:46 2003  Matthias Clasen  <maclas@gmx.de>

	* glib/gconvert.c (get_filename_charset): Replacement for
	have_broken_filenames() which consults the environment variable
	G_FILENAME_ENCODINGS in addition to G_BROKEN_FILENAMES.
	* glib/gconvert.c (g_filename_from_utf8):
	* glib/gconvert.c (g_filename_to_utf8):
	* glib/gconvert.c (_g_convert_thread_init): Use
	get_filename_charset() instead of have_broken_filenames().
