Defined in header <wctype.h>
int iswprint( wint_t ch );		(since 哋它亢95)

Checks if the given wide character can be printed, i.e. it is either a number (0123456789), an uppercase letter (ABCDEFGHIJKLMNOPQRSTUVWXYZ), a lowercase letter (abcdefghijklmnopqrstuvwxyz), a punctuation character (!"#$%&'()*+,-./:;<=>?@[\]^_`{!}~), space or any printable character specific to the current C locale.

Parameters

ch

-

wide character

Return value

Non-zero value if the wide character can be printed, zero otherwise.

Notes

ISO 30112 specifies which Unicode characters are included in POSIX print category.

Example

Run this code

#include <locale.h>
#include <stdio.h>
#include <wchar.h>
#include <wctype.h>
 
int main(void)
{
    wchar_t c = L'\u2002'; // Unicode character 'EN SPACE'
    printf("in the default locale, iswprint(%#x) = %d\n", c, !!iswprint(c));
    setlocale(LC_ALL, "en_US.utf8");
    printf("in Unicode locale, iswprint(%#x) = %d\n", c, !!iswprint(c));
    wchar_t c2 = L'\x82'; // break permitted
    printf("in Unicode locale, iswprint(%#x) = %d\n", c2, !!iswprint(c2));
}

Output:

in the default locale, iswprint(0x2002) = 0
in Unicode locale, iswprint(0x2002) = 1
in Unicode locale, iswprint(0x82) = 0
