key detection with SDL library

hello

I am making a chat program which (obviously) needs to detect the ascii of the key pressed.

Unfortunately I can get only the ascii of the "real" key pressed.
I don't know how to explain that, so here's an example:

when the user presses just <a>, SDL gives me the code 97 (which is the correct ascii code for "a")
if the user presses <SHIFT + a>, SDL again gives me 303 (the R-SHIFT code used by SDL) and again 97.

ok, I simply might recognize when the user presses shift, which is not a hard deal but...
if I have to check for non-alphabetical keys?
here is the complication, explained with a comparation:

italian user presses <9> : ascii code is 57
english user presses <9> : ascii code is 57

italian user presses <SHIFT + 9> : character is ")", ascii code is 41
english user presses <SHIFT + 9> : character is "(", ascii code is 40

I've already tried to implement a function which detects the input, but there happen some conflicts with SDL.
also my knowledge with low-level C coding is not good.

Which way should I start from? thanks

edit: I'd also be glad to make it portable

edit solved: ok, nevermind, I've just found the perfect solution:

This is the code (found somewhere in the net) from which I've extracted a function to be used by my program.
Even studying it, I still don't understand the great part of these lines...
By the way I guess this program deals with the terminal specifically, which is not what I really need, am I wrong?

Code:

---

#include <termios.h>
#include <iostream>

int main(void)
{
        int count;
        int jndex;
        int result;
        int virgin;

        char echoed_data;
        char in_buffer[80];

        struct termios tp1;
        struct termios tp2;

        virgin=1;
        echoed_data='X';

        printf("Type a space character to exit.\n");

        tcgetattr(0,&tp1);

        tp2=tp1;

        tp2.c_iflag&=~ICRNL;
        tp2.c_lflag&=~ICANON;
        tp2.c_lflag&=~ECHO;
        tp2.c_cc[VMIN ]=1;
        tp2.c_cc[VTIME]=0;
        tp2.c_cc[VINTR]=0xFF;
        tp2.c_cc[VSUSP]=0xFF;
        tp2.c_cc[VQUIT]=0xFF;

        tcsetattr(0,TCSANOW,&tp2);

        do {
                in_buffer[0]=0;

                count=read(0,in_buffer,1);

                if(virgin)
                {
                        virgin=0;
                        tp2.c_cc[VMIN]=0;
                        tcsetattr(0,TCSANOW,&tp2);
                }

                if(count>0)
                        echoed_data=in_buffer[0];

                printf("&#37;d: ", echoed_data);
                printf("%d\n", 256 + echoed_data);

                fflush(stdout);

        } while(echoed_data!=0x20);

        printf("\n");

        tcsetattr(0,TCSANOW,&tp1);

        return 0;

}

You probably want to use SDL events, and in particular SDL KeyboardEvent

Search the web for those two, and you will find more info.

Thank you matsp
That's it. I didn't search enough :)
