What if there is a line break between the two characters joined by a
double width combining character?
Are arbitrary line breaks in the middle of words actually permitted
anyway? Presumably any line breaking property of the first base
character of the pair is cancelled anyway. That leaves a problem only if
the second base character has a line break before possibility. Well,
that could just be treated as one of the sequences we were discussing
yesterday, not illegal Unicode but its rendering is undefined.
