title: Remove character '\u202A' 8234 from string
body: <p>I am trying to get character at 0 index in a string:</p>
  
  <pre><code>public static String editNoHP (String noHP){
    String result;
    try {
        if(noHP.charAt(0) == '0')
            result = "62"+noHP.substring(1);
        else if(noHP.charAt(0) == '+' )
            result = noHP.substring(1);
        else if(noHP.charAt(0) == '6')
            result = noHP;
        else if(noHP.charAt(0) == '6' &amp;&amp; noHP.charAt(1) == '2')
            result = noHP;
        else if(noHP.charAt(0) == '9')
            result = noHP;
        else
            result = "62"+noHP;
    }
    catch (Exception e){
        return "";
    }
  
    return result.replaceAll("[\\s\\-\\.\\^:,]","");
  }
  </code></pre>
  
  <p>So I use this function after I query contact, but I found strange result.</p>
  
  <p>Normal input &amp; output:</p>
  
  <pre><code>input = +62 111-1111-1111   output : 6211111111111
  input = 011111111111        output : 6211111111111
  </code></pre>
  
  <p>And this the strange input and result:</p>
  
  <pre><code>input = 011111111111        output : 62011111111111
  </code></pre>
  
  <p>So I try to debug this account and I found when app try to get character at 0 the return is '\u202A' 8234, not 0.</p>
  
  <p>I already tried RegEx like:</p>
  
  <pre><code>String clean = str.replaceAll("[^\\n\\r\\t\\p{Print}]", ""); or
  String clean = str.replaceAll("[^\\x20-\\x7E]", ""); or
  String clean = str.replaceAll("[^\u0000-\uFFFF]", ""); or
  String clean = str.replaceAll("[^\\p{ASCII}]", ""); or
  String clean = str.replaceAll("[^\x00-\x7F]", ""); or
  String clean = StringEscapeUtils.unescapeJava(str);
  </code></pre>
  
  <p>All of them return same value '\u202A' 8234.</p>
  
  <p>What is this character?
  How to fix this problem?</p>
  
  <p>Update :
  I try to edit the strange contact and I found strange behaviour. The number is 011111111111. First I put cursor between 0 and 1, then I press delete/backspace to remove 0. The cursor suddenly move to the right of number 1 not on the left. Then I save the contact and run my program. The result is 0, not '\u202A' 8234. So I think this because the format of number not normal, maybe when first time add this contact or when sync from the google account.</p>
