Preventing ANSI Escape Characters in Keyboard Input in C

I have a C program that asks the user for their name with a bit of code that reads from stdin on a while loop (until enter is pressed). I am making sure the user can only enter ASCII values from 32 to 126.

The problem is when I press my arrow (cursor) keys, or something like PAGE_DOWN or other... I end up having the ANSI escape sequence printed to the terminal ([A, [6~, etc.).

Here is the section of code.

char name[6];
char c;
uint8_t i = 0;
while ((c = getchar()) != '\n') {
    if (c == 127 || c == 8) {   // Checks if backspace or del is pressed
        i--;
        name[i] = ' ';
    } else if (c >= 32 && c <= 126) {   // Only legal key presses please!
        name[i] = c;
        i++;
    } else {

    }

    if ((c >= 32 && c <= 126) || c == 127 || c == 8) {
        printf_P(PSTR("%c"), c);
    }
}
name[5] = '\0';
move_cursor(15, 18);
printf_P(PSTR("%s"), name);

I have certainly chosen to ignore ASCII values outside the 32 to 126 range, so what is the cause of this? Any ideas? Cheers!
