Read/Write Spanish special characters (accents, ñ,...) in a C console application

  • 772

I am trying to make a C console application collect (via keyboard) special Spanish characters like accents, 'ñ', etc in a scanfor in gets.

I have managed to display these characters correctly (stored in a variable or, directly, from the printf) thanks to the locale.h. I show an example:

#include <stdio.h>
// Añade paquete de idiomas
#include <locale.h>

int main(void)
{
    // Declaración de variables
    char cadena[254];

    // Establecer el idioma a español
    setlocale(LC_ALL, "spanish");

    // Mostrar correctamente los caracteres especiales del español
    printf("¡Éxito!. Se muestran los caracteres especiales del español.");

    printf("Introduce un string con caracteres especiales: ");
    gets(cadena);

    printf("El string con caracteres especiales que has introducido es: %s", cadena);

    return 0;   
}

but I still couldn't get them to be picked up correctly with the functions mentioned above.

Does anyone know how to do it?

Thank you

EDIT 1:

Doing tests I have observed that:

  • setlocale(LC_ALL, "spanish");It shows the Spanish characters correctly, but it doesn't pick them up from the keyboard.
  • setlocale(LC_ALL, "es_ES");It collects the Spanish characters correctly from the keyboard, but it does not display them correctly.

    I have found a solution to the problem. Apparently this problem only appears in Windows and its command console.

    #include <stdio.h>
// Añade paquete de idiomas
#include <locale.h>
#include <windows.h>

int main(void)
{
    // Declaración de variables
    char cadena[254];

    // Establecer el idioma a español
    setlocale(LC_ALL, "spanish"); // Cambiar locale - Suficiente para máquinas Linux
    SetConsoleCP(1252); // Cambiar STDIN -  Para máquinas Windows
    SetConsoleOutputCP(1252); // Cambiar STDOUT - Para máquinas Windows

    // Mostrar correctamente los caracteres especiales del español
    printf("¡Éxito!. Se muestran los caracteres especiales del español.");

    printf("Introduce un string con caracteres especiales: ");
    gets(cadena);

    printf("El string con caracteres especiales que has introducido es: %s", cadena);

    return 0;   
}

    It consists of changing the encoding of both input and output of the windows console with the commands SetConsoleCP()and SetConsoleOutputCP()(for this it is also necessary to include the header windows.h). With that the problem is solved. I hope it helps other people who have the same problem as me.

    All the best.
