    The __ctype_toupper_loc() function shall return a pointer into an array
    of characters in the current locale that contains upper case equivalents
    for each character in the current character set. The array shall contain
    a total of 384 characters, and can be indexed with any signed or unsigned
    char (i.e. with an index value between -128 and 255). If the application
    is multithreaded, the array shall be local to the current thread.

    standard.
