BabelStone Han v. 15.1.3 supports the following set of four Han ligatures, produced by inserting U+200D Zero Width Joiner (ZWJ) between the two characters to be ligatured. Ligatures such as these occupy a single character space, but are read as two separate characters, and are considered a presentation form of the unligatured characters. As such they are not suitable for separate encoding as CJK unified ideographs.
