I guess we can if they actually bother to conform to C99. 6.4.3
Universal character names:
The universal character name \Unnnnnnnn designates the character
whose eight-digit short identifier (as specified by ISO/IEC 10646)
is nnnnnnnn. Similarly, the universal character name \unnnn
designates the character whose four-digit short identifier is nnnn
(and whose eight-digit short identifier is 0000nnnn).
Note that it doesn't say here that L'\u23bd' should be equal to 0x23bd.
