  String.graphemes().count()

That's a real nice API. (Similarly, python has @ for matmul but there is not an implementation of matmul in stdlib. NumPy has a matmul implementation so that the `@` operator works.)

ugrapheme and ucwidth are one way to get the graphene count from a string in Python.

It's probably possible to get the grapheme cluster count from a string containing emoji characters with ICU?

Any correctly designed grapheme cluster handles emoji characters. It’s part of the spec (says the guy who wrote a Unicode segmentation library for rust).
