Escape sequences not working correctly for the C language about ide

Hi @gouseferoz,

I can confirm that I can reproduce your issue.

But let's see what happens when we do this in a terminal locally.

1. Create a file main.c with the following content:

#include <stdio.h>

int main(void) 
{
    printf("123\b45\n");
    return 0;
}

2. Compile it:

gcc main.c

3. Run it to get the expected results:

herman@zlata:test$ ./a.out 
1245

4. Now redirect the output to a file out.txt to get again expected result after cut command.

herman@zlata:test$ ./a.out > out.txt
herman@zlata:test$ cat out.txt
1245

5. But, let's see what is written inside the out.txt file:

herman@zlata:test$ vim out.txt

You will see a sequence that looks like this: 123^H45.

I.e. if you open it with gedit or some other editor you will see 123�45 as you noticed.

Also, if we take a look at what Judge0 API is returning as a stdout for a submission that contains above source code we can notice that the content of stdout is exactly what we see in the file out.txt.

Conclusion. Judge0 IDE does not work as a terminal that obviously knows how to work with the characters like \b. Judge0 IDE just shows you the content of a "file" that is the result of your submission.

I currently don't know how to make Judge0 IDE output pane behave as the terminal. Any suggestions are welcome.
