How to remove surrogate characters in Java?

Question

I am facing a situation where i get Surrogate characters in text that i am saving to MySql 5.1. As the UTF-16 is not supported in this, I want to remove these surrogate pai

Answer 1

Just curious. If char is high surrogate is there a need to check the next one? It is supposed to be low surrogate. The modified version would be:

public static String removeSurrogates(String query) {
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < query.length(); i++) {
        char ch = query.charAt(i);
        if (Character.isHighSurrogate(ch))
            i++;//skip the next char is it's supposed to be low surrogate
        else
            sb.append(ch);
    }    
    return sb.toString();
}
