Encoding in sprintf

In the following code:

char test[50];
sprintf(test, "áéíóú");

is there a way to make sprintf interpret input characters as Windows-1252 instead of Unicode? I mean, to make test contain 0xE1E9EDF3FA... instead of 0xC3A1C3A9C3ADC3B3C3BA...

#include <stdio.h>
#include <stdlib.h>

size_t utf2bin(unsigned char *dst, unsigned char *src, size_t dstlen);

int main (void)
{
unsigned char src[] = {0xC3, 0xA1, 0xC3, 0xA9, 0xC3, 0xAD, 0xC3, 0xB3, 0xC3, 0xBA, 0};
unsigned char dst[100];
size_t ret;

// ret = mbstowcs(dst,src, sizeof dst);
// ret = wcstombs(dst,src, sizeof dst);
ret = utf2bin(dst,src, sizeof dst);

printf("Src=%s.\n", src );
printf("Dst=%s.\n", dst );

return 0;
}

size_t utf2bin(unsigned char *dst, unsigned char *src, size_t dstlen)

size_t pos;

You have to edit this from inside your text editing program. This is a matter of the actual file that contains your source code.

To do that in most editors and IDEs there is a menu called ENCODING

EDIT: More specifically for Geany, which appears to be the software you are running go to:

Document >> Set Encoding >> West European >> Western (1252)
