Example

See the notes at the beginning of this chapter or section for information on using printf() or scanf() (and other functions reading and writing the stdin or stdout streams) in the example code.

#include <stdio.h>
#include <stdlib.h>
#include <wchar.h>
#include <locale.h>
 
#define SIZE 40
 
int main(void)
{
  static char  buffer[SIZE];
  wchar_t * wch = L"PIC®";
  int length, idx;
 
  setlocale(LC_CTYPE, "");
  while(wch[idx]) {
    length = wctomb(buffer, wch[idx]);
    printf( "bytes in multibyte %lc is %i\n", wch[idx], length);
    printf( "converted string \"%s\"\n", buffer);
    idx++;
  }
}

bytes in multibyte P is 1
converted string "P"
bytes in multibyte I is 1
converted string "I"
bytes in multibyte C is 1
converted string "C"
bytes in multibyte ® is 2
converted string "®"
