mail handler failing when smilies inline
My system info:

I am using mail aliases to pipe mail to mailhandler.
Unfortunately it fails when an e-mail contains an emoji/smiley see attached.
In receiving replay form server it initially is reported as possible permission problem:
The mail system <firstname.lastname@example.org>: permission denied. Command output: Request was denied by your Redmine server. Possible reasons: email is sent from an invalid email address or is missing some information.

but further investigations shows:
MailHandler: an unexpected error occurred when receiving email: Mysql2::Error: Incorrect string value: '\xF0\x9F\x98\x8A' for column 'description' at row 1: INSERT INTO `issues` (`tracker_id`, `project_id`, `subject`, `description`, `status_id`, `assigned_to_id`, `priority_id`, `author_id`, `created_on`, `updated_on`, `start_date`, `lock_version`) VALUES (3, 6, 'Fwd: Fwd: FW: Forems', 'Ttestam\r\n\r\nItkā sīkums, bet ja to var sakārtot, varbūt ir vērts

Quote from Marius BALTEANU in #34574#note-4:
The smiley issue is generated by your database configuration, most probably you are using MySQL with a column encoding such as utf8 which can not store 4-Byte unicode characters (such as most emojis or special characters) If that is the case, see #10772.
In Redmine 4.1 we fixed this problem for new fresh installations (#31921), but for existing installations, before making that change, you need to migrate your database. In the mentioned tickets, you can find various links to articles that describe the process. Please be aware that it's a sensitive process and I highly recommend to backup your data before proceeding.
Please reopen if I'm wrong.
