True if this object contains valid extended grapheme cluster.
Decoding primitives of this module always return a valid Grapheme.
Appending to and direct manipulation of grapheme's $(CHARACTERS) may
render it no longer valid. Certain applications may chose to use
Grapheme as a "small string" of any $(CODEPOINTS) and ignore this property
entirely.
