-	[UVS] Stabilizes UVS supporting functions against non-UVS fonts.
-
-	UVS supporting functions assume the variation handler functions
-	are valid.  When fonts without cmap format 14 is given, these
-	function pointers are left as NULL, so calling these functions
-	causes NULL pointer dereference.
-
-	* src/base/ftobjs.c (FT_Face_GetCharVariantIndex): Check the pointer
-	FT_CMap_Class->char_var_index before calling it.
-	(FT_Face_GetCharVariantIsDefault): Check the pointer
-	FT_CMap_Class->char_var_default before calling it.
-	(FT_Face_GetVariantSelectors): Check the pointer
-	FT_CMap_Class->variant_list before calling it.
-	(FT_Face_GetVariantsOfChar): Check the pointer
-	FT_CMap_Class->charvariant_list before calling it.
-	(FT_Face_GetCharsOfVariant): Check the pointer 
-	FT_CMap_Class->variantchar_list before calling it.
