	* configure.in (PACKAGE): move $enable_debug down below
	checks for GCC to avoid setting CFLAGS prematurely,
	change checks to avoid adding -g twice.

	* gutf8.c (g_ucs4_to_utf8): Support len < 0 to mean
	0 termination.

	* gutf8.c (g_utf8_to_ucs4): Terminate result with 0.

	* tests/mainloop-test.c (main): Fix uses of
	g_main_loop_destroy().

	* tests/unicode-encoding.c tests/Makefile.am tests/utf8.txt:
	Tests for unicode-conversion code.

	* gconvert.c (g_convert, g_convert_with_fallback): work around
	a couple of GNU libc bugs.

	* gconvert.[ch] (g_{locale,filename}_{to,from}_utf8): Standardize
	arguments to match g_convert(). Document.

	* gunicode.[ch]:
	  - Implement conversion functions to and from UTF-16
	  - Standardize unicode conversion functions on prototype like
	    g_convert.
	  - Add a lot of error checking to unicode conversion functions.

	* gunicode.[ch] (g_utf8_to_ucs4_fast): Add fast, non-checking
	variant of g_utf8_to_ucs4.

	* gutf8.c (g_utf8_validate):
	 - add g_return_if_fail (str != NULL).
	 - add checks for overlong strings, non-valid Unicode characters (>= 110000)
	   and single surrogates.
