1 seems like the only acceptable answer. For all intents and purposes, a user will count it as one character. Truncating the string without including the whole cluster would change the meaning of it, and is not an operation anyone would do as a general purpose thing any more than someone would want to randomly replace the last character with random letters. It looks like one character. I'd rather APIs let us continue pretending it is one character.
