	* libgimpbase/gimputils.[ch]: new function which takes any string
	and returns UTF-8 (it returns "(invalid UTF-8 string)" if all
	conversion attempts fail).

	* app/core/gimpbrush.c
	* app/core/gimpgradient.c
	* app/core/gimppalette.c
	* app/core/gimppattern.c
	* app/xcf/xcf-read.c: use it. Fixes bug #79897.
