Detect unicode

[Avik Sengupta]

We currently have two methods to detect unicode characters. Which is
better? Primarily on performance. I want to consolidated. There might be
other such code scattered! 

public static boolean hasMultibyte(String value){
if( value == null )return false;
for(int i = 0 ; i  value.length() ; i++ ){
char c = value.charAt(i);
if(c  0xFF )return true;
}
return false;
}

 public static boolean isUnicodeFormat(final String format) {
try {
  return !format.equals( new String(format.getBytes (ISO-8859-1),
ISO-8859-1));
} catch (UnsupportedEncodingException e) {
  return true;
}
  }

Re: Detect unicode

I'm betting on the latter.  I think the former is legacy code from when 
we supported 1.22 or something.
