Unicode is a numbering of all characters. The numbering would need three bytes integers. A Unicode character is represented in science as U+XXXX where XXXX stands for the number in hexadecimal (base 16) notation. A Unicode character is called code point, in Java with type int.

Java char is 2 bytes (UTF-16), so cannot represent the higher order Unicode; there a pair of two chars is used.

The java class Character deals with conversion.

char lowUnicode = '\u0627'; // Alef, fitting in a char
int cp = (int) lowUnicode;

One can iterate through code points of a String as follows:

    String s = "...";
    for (int i = 0; i < s.length(); ) {
        int codePoint = s.codePointAt(i);
        i += Character.charCount(codePoint);
    }

    String s = "...";
    for (int i = 0; i < s.length(); ) {
        int codePoint = s.codePointAt(i);
        ...
        i += Character.charCount(codePoint);
    }

Or in java 8:

    s.codePoints().forEach(
        (codePoint) -> System.out.println(codePoint));

Dumping Arabic between U+600 and U+8FF:

The code below dumps Unicode in the main Arabic range.

for (int codePoint = 0x600; codePoint < 0x900; ++codePoint) {
    if (Character.isAlphabetic(codePoint)
            && UnicodeScript.of(codePoint) == UnicodeScript.ARABIC) {

        System.out.printf("\u200E\\%04X \u200F%s\u200E %s%n",
                codePoint,
                new String(Character.toChars(codePoint)),
                Character.getName(codePoint));
    }
}

Under Windows/Linux/... there exist char map tools to display Unicode. Above U+200E is the Left-To-Right, and U+200F is the Right-To-Left mark.

If you want to get Unicode characters code below will do that:

char character = 'ع';
int code = (int) character;
