回答1:

Android native its java, so.. check this:

You can do it for any Java char using the one liner here:

System.out.println( "\\u" + Integer.toHexString('÷' | 0x10000).substring(1) );

Reference: Get unicode value of a character

I hope that I have helped answer some of your questions.

Use Apache Commons Lang api. StringEscapeUtils.escapeJava() can help you get the answer.

import org.apache.commons.lang3.StringEscapeUtils;

public class StringUnicode {

    public static void main(String[] args) {

        String foreignText = "برنامه نویسی";

        String response = StringEscapeUtils.escapeJava(foreignText);
        System.out.println(response);
    }
}
