mb_convert_encoding(): Illegal character encoding specified

[ascendroGitHub]

Hi,
Can you please help me, I think this is a bug:

Steps to reproduce:

1. Connected via POP3/IMAP to a maibox
2. Selected INBOX folder
3. request: ->getMessagesByCriteria('', 50)
4. Exception Error is catched to an email:
   yii\base\ErrorException Object
   (
   [message:protected] => mb_convert_encoding(): Illegal character encoding specified
   [string:Exception:private] =>
   [code:protected] => 2
   [file:protected] => C:\Work\wamp64\www\workflow-assistant\vendor\ssilence\php-imap-client\ImapClient\IncomingMessage.php
   [line:protected] => 392
   )

charset = null

Did you ever get anywhere with this? I'm having the same problem. Line 400 of IncomingMessage.php is failing:

$objNew->text = quoted_printable_decode(mb_convert_encoding( $objNew->plain, "utf-8", $objNew->plain->charset ));

I am having the same issue:

mb_convert_encoding(): Illegal character encoding specified in IncomingMessage.php line 400

$objNew->text = quoted_printable_decode(mb_convert_encoding( $objNew->plain, "utf-8", $objNew->plain->charset ));
