iswprint - test for a printable wide-character code
The iswprint() function shall test whether wc is a wide-character code representing a character of class print in the program's current locale; see the Base Definitions volume of IEEE Std 1003.1-2001, Chapter 7, Locale.
The wc argument is a wint_t, the value of which the application shall ensure is a wide-character code corresponding to a valid character in the current locale, or equal to the value of the macro WEOF. If the argument has any other value, the behavior is undefined.
No errors are defined.
