public static void main(String[] args)
{
int i=153;
int j=63;
System.out.println((char)i);
System.out.println((char)j);
}
OUTPUT:-
?
?
I have some i
ASCII 153
(0x99
) is different from Unicode U+0099
(Control character).
This program should do what you intend it to do:
public class ExtendedAscii {
public static final char[] EXTENDED = { 0x00C7, 0x00FC, 0x00E9, 0x00E2,

public static final char getAscii(int code) {
if (code >= 0x80 && code <= 0xFF) {
return EXTENDED[code - 0x7F];
}
return (char) code;

public static final void printChar(int code) {
System.out.printf("%c%n", getAscii(code));
}
public static void main(String[] args) {
printChar(153);
printChar(63);
}
}
Output:

?
As you can see from the output above, the intended character gets printed correctly.
Also, I wrote a program that prints out the Unicode values for the extended Ascii. As you can see in the output below, a lot of characters have trouble being displayed as native char
.
Code:
public class ExtendedAscii {
public static final char[] EXTENDED = { 0x00C7, 0x00FC, 0x00E9, 0x00E2,
