notice issued when string is empty

[GoogleCodeExporter]

  public static function fromString16($value)
  {
      if ($value[0] == 0xfe && $value[1] = 0xff)
        return self::fromString16BE(substr($value, 2));
      else
        return self::fromString16LE(substr($value, 2));
  }

This chokes if $value is an empty string.  I made the following change to get 
rid of the notices:

  public static function fromString16($value)
  {
    if(strlen($value) == 0)
        return '';

      if ($value[0] == 0xfe && $value[1] = 0xff)
        return self::fromString16BE(substr($value, 2));
      else
        return self::fromString16LE(substr($value, 2));
  }

This occurred with the following two lines of code:
require_once("ID3v2.php");
$id3 = new ID3v2('/path/to/file.mp3');
