I have a big problem on using unicode.
I know to process Unicode I should do like this:
JLabel Label = new Label("\u0645");

but the problem is that I want to do this dynamicly.
Imagine that you want to get the ASCII code from Input ,then you
want to convert the ASCII Code to Unicode so you do like this:

int input = ???; // you get the input

byte[] b = new byte[1];
b[0] = 92; // ASCII Code "92" is "\" Character
String s = new String(b); // so "s" become "\"

//Imagine we have a method which get the integer then parse String
as Hexa mode of Decimal
String Hexa = convertDecToHex(input);

JLabel Label = new Label(s+"u06"+Hexa);

if you do like this you will find different result;
I mean: "JLabel Label = new Label(s+"u06"+Hexa)" is different
by "JLabel Label = new Label("\u06xx") "

but 's+"u06"+Hexa' produce '\u06xx'
