E-mail and UTF-8, mb_, etc.

My comments about multi-byte handling still stands, I created my own setMessageText() function that is a mix of what was there and something that handles <br/> and <p></p>. This assumes I send my message as HTML:

PHP Code:

public static function setMessageText( string $message_text ) : void {
        self::checkSetup();
        self::$email->setAltMessage( '' );
        self::$email->setMessage( $message_text );

        $plain_text = mb_eregi_replace( '<br(\s?\/)?>', "\n", $message_text );
        $plain_text = mb_eregi_replace( '<p>', "\n", $plain_text );
        $plain_text = mb_eregi_replace( '</p>', "\n\n", $plain_text );

        $plain_text = preg_match('/\<body.*?\>(.*)\<\/body\>/si', $plain_text, $match) ? $match[1] : $plain_text;
        $plain_text = str_replace("\t",
                                  '',
                                  preg_replace('#<!--(.*)--\>#',
                                              '',
                                              trim( strip_tags( $plain_text ) )
                                  )
        );

        self::$email->setAltMessage( $plain_text );
    }
