Fix non-ascii characters in outgoing e-mails

[tuxmartin]

Hi, I'm using feature IMAP Folder To Save Outgoing Replies.

But if I open my mailbox using webmail/thunderbird, all outgoing e-mails have header Content-Type: TEXT/html; CHARSET=US-ASCII.

I have email signature with non-ascii chars. Can you please use UTF-8 or encode non-ascii chars?

Will the customer see my email without errors? I'm afraid thatthe customer will see the broken characters.

Facing the same issue. In Germany we have a mark put over a vowel like äöü. These letters are also not properly displayed.

It would be great if you could fix this 👍

If you add $part1['charset'] = 'utf-8'; here https://github.com/freescout-helpdesk/freescout/blob/168c61e4b00ec38ca79b22f139710025adb89437/app/Jobs/SendReplyToCustomer.php#L294

it seemed to be fixed. Also adding

$envelope['date'] = now()->toRfc2822String();
$envelope['message_id'] = $this->message_id;

might be useful for proper listing in several clients (we had some trouble with the date indicator). I also noted that attachments are completly ignored (?)

@freescout-helpdesk If my suggestion is appropriate, I would love to see the addition for charset, date and message_id in a upcoming update.
