JSR 204 added new methods in the Character class to
support supplementary characters in Java identifiers, but these methods
only check a single character at a time. It would be beneficial to have
a method that takes a complete String or CharSequence and checks
whether it's a valid Java identifiers. Such a method would greatly
increase the chances that tools in general will correctly handle
supplementary characters in identifiers.
