Huh, that feels like a bug to me, since it can also return false, which 
is the more standard way of indicating failure.

The obvious failure case is an input string that's not valid UTF-8, e.g. 
grapheme_strlen("\xFF"). It appears that currently returns null; so I'm 
not actually sure how you'd trigger the false case.
