  30 /* [lex.charset]: The character designated by the universal character
  31    name \UNNNNNNNN is that character whose character short name in
  32    ISO/IEC 10646 is NNNNNNNN; the character designated by the
  33    universal character name \uNNNN is that character whose character
  34    short name in ISO/IEC 10646 is 0000NNNN.  If the hexadecimal value
  35    for a universal character name is less than 0x20 or in the range
  36    0x7F-0x9F (inclusive), or if the universal character name
  37    designates a character in the basic source character set, then the
  38    program is ill-formed.
  39
  40    *PSTR must be preceded by "\u" or "\U"; it is assumed that the
  41    buffer end is delimited by a non-hex digit.  Returns zero if UCNs
  42    are not part of the relevant standard, or if the string beginning
  43    at *PSTR doesn't syntactically match the form 'NNNN' or 'NNNNNNNN'.
  44
  45    Otherwise the nonzero value of the UCN, whether valid or invalid,
  46    is returned.  Diagnostics are emitted for invalid values.  PSTR
  47    is updated to point one beyond the UCN, or to the syntactically
  48    invalid character.
  49
  50    IDENTIFIER_POS is 0 when not in an identifier, 1 for the start of
  51    an identifier, or 2 otherwise.
