Determines whether the specified character (Unicode code point) is mirrored according to the Unicode specification.

Usage

From source file:Main.java

public static void main(String[] args) {
    int cp1 = 0x0c01;
    int cp2 = 0x003c;

    boolean b1 = Character.isMirrored(cp1);
    boolean b2 = Character.isMirrored(cp2);

    System.out.println((char) cp1 + " represents a mirrored character is " + b1);
    System.out.println((char) cp2 + " represents a mirrored character is " + b2);
}
