incomplete specification for Character.isMirrored(ch)

Name: ooR10006 Date: 01/08/2001


The jdk1.4.0beta-b45 API specification for method Character.isMirrored(ch)
doesn't specify the return value for undefined chars.
Unicode3.0 standard doesn't specify mirrored property for undefined chars.
jdk1.4.0beta-b45 API implementation returns value false for all undefined chars.
The following simple test shows this:

public class test {
    public static void main(String[] args){
        String str = "";
        for (int i = 0; i <= 65535; ++i){
            if (Character.isDefined((char)i) != true){
                str += " " + Character.isMirrored((char)i);
            }
        }
        System.out.println(str);
    }
}
