* include/grub/normal.h (grub_utf8_to_ucs4): New declaration.
	(grub_print_ucs4_alloc): Likewise.
	(grub_getstringwidth): Likewise.
	* normal/main.c (grub_normal_init_page): Gettextize version string.
	* normal/menu_text.c (grub_utf8_to_ucs4_alloc): New definition.
	(getstringwidth): Renamed to ...
	(grub_getstringwidth): ... this. Remove `static' qualifier (now used
	in normal/main.c).  Use `grub_utf8_to_ucs4_alloc'.
	(grub_print_ucs4): Remove `static' qualifer (now used in
	normal/main.c).
