In more technical terms, my question was whether these symbols form extended grapheme clusters. In WebCore, these are returned by characterBreakIterator, which just calls ICU.

We sometimes allow cursor positioning inside extended grapheme clusters. We should probably never disallow cursor positioning at a place where a character break can occur (e.g. for truncation).
