If this is so: why did my compiler not tell me about this?

Why does this:
        NSString *string = @"abc 〄 xyz";        // JAPANESE INDUSTRIAL STANDARD 
SYMBOL = U+3004
        NSCharacterSet *charSet = [ NSCharacterSet 
characterSetWithCharactersInString: string ];
        BOOL pq = [ charSet longCharacterIsMember: 0x3004 ];
        NSLog(@"%s CharacterSet from \"%@\" contains %s〄 
(0x3004)",__FUNCTION__,  string, pq ? "" : "no ");


print: 
CharacterSet from "abc 〄 xyz" contains 〄 (0x3004)


Kind regards,

Gerriet.
