wint_t towupper( wint_t wc );

(since C95)

Converts the given wide character to uppercase, if possible.

[edit] Parameters wc - wide character to be converted [edit] Return value

Uppercase version of wc or unmodified wc if no uppercase version is listed in the current C locale.

[edit] Notes

Only 1:1 character mapping can be performed by this function, e.g. the uppercase form of 'Ã' is (with some exceptions) the two-character string "SS", which cannot be obtained by towupper.

ISO 30112 specifies which pairs of Unicode characters are included in this mapping.

[edit] Example

#include <stdio.h>
#include <wchar.h>
#include <wctype.h>
#include <locale.h>
 
int main(void)
{
    wchar_t wc =  L'\u017f'; // Latin small letter Long S ('Å¿')
    printf("in the default locale, towupper(%#x) = %#x\n", wc, towupper(wc));
    setlocale(LC_ALL, "en_US.utf8");
    printf("in Unicode locale, towupper(%#x) = %#x\n", wc, towupper(wc));
}

Output:

in the default locale, towupper(0x17f) = 0x17f
in Unicode locale, towupper(0x17f) = 0x53
