If a character can't be converted, don't replace it with a NUL byte, but

2006-08-05  Matthias Clasen  <mclasen@redhat.com>

	* glib/guniprop.c (g_unichar_toupper, g_unichar_tolower)
	(real_toupper, real_tolower): If a character can't be converted,
	don't replace it with a NUL byte, but leave it unchanged.
	(#348491, Nikolai Weibull)

	* tests/unicode-caseconv.c: Adapt to this change.

	* tests/unicode-caseconv.c (main): Add a comment to point out
	a quirk in the test data that we are working around here.
