// This function classifies an universal character value into 4 subranges:
// universal_char_type_valid
// the universal character value is valid for identifiers
// universal_char_type_invalid
// the universal character value is not valid for its usage inside
// identifiers (see C++ Standard: 2.2.2 [lex.charset])
// universal_char_type_base_charset
// the universal character value designates a character from the base
// character set
// universal_char_type_not_allowed_for_identifiers
// the universal character value is not allowed in an identifier
//
// Implementation note:
// This classification isn't implemented very effectively here. This
// function should be rewritten with some range run matching algorithm.
