How to detect if a string contains any Right-to-Left character?

Question

I'm trying to make a method to detect strings written in right to left languages in Java. I've come up with this question doing something similar in C#.
Now I need to have something like that but written in Java.
Any help is appreciated.

Answer 1

I came up with the following code:

char[] chars = s.toCharArray();
for(char c: chars){
    if(c >= 0x600 && c <= 0x6ff){
        //Text contains RTL character
        break;
     }
}

It's not a very efficient or for that matter an accurate way but can give one ideas.
