Printf打印错误的特殊字符

Question

I am working in a C/C++ code that casts a char to its integer value and then needs to print it back to its char value.

But, when I try to print an "Extended ASCII" character using the printf function, it shows a different character and I can't figure out what's wrong.

int charInt = (int) 'á'; // -31
char casted = (char) charInt;
printf("%c\n", casted); // ß

If I debug the code (I'm using Visual Studio 2017), the variable ' casted ' shows the correct 'á' value in IntelliSense.

I tested some different ways of printing this character, but it always has the same result:

printf("test: %d\n", (signed char)'á');   // -31
printf("test: %d\n", (unsigned char)'á'); // 225
printf("test: %c\n", -31); // ß
printf("teste: %s\n", "á"); // ß
printf("test: %c\n", 225); // ß
printf("test: %d\n", 'á'); // -31
putc(-31, stdout); // ß

What I am doing wrong ?

It was a locale problem, as said in the comments of my question.

I just needed to use setlocale() and the output in the console worked.
