I think this is fine, although it doesn't appear to be a valid tailoring
of UAX#14, either.

I don't understand this property, and do not want to add a new property.

> One of the experts recommended ID (Ideographic) class[2] for inline images such as Emoji. One idea is to have a boolean property to opt-in to this behavior. Another idea was to for authors to specify UAX#14 class. Among the three options, I think the 1 character length string gives the best flexibility.

Is there a reason we can't just treat as ID always?
