Answer 1

Replace this code in you file

\system\libraries Email.php file

public function subject($subject)
{
  $subject = $this->_prep_q_encoding($subject);
  $this->set_header('Subject', $subject);
  return $this;
}

To

public function subject($subject)
{
   $subject = '=?UTF-8?B?'.base64_encode($subject).'?=';
   $this->_set_header('Subject', $subject);
   return $this;
}

and set the email configuration in your email config

$config = array(
    'protocol' => 'smtp',
    'charset' => 'utf-8',
    'newline' => "\r\n",
    'crlf' => "\n",
    'mailtype' => "html"
);
