[MM3-users] Re: hyperkitty: "incorrect string value" for botched utf-8 encoding

The underlying issue has been seen before. The basic problem is in MySQL and MariaDB the encoding is utf8 which only accepts utf8 encodings up to 3 bytes. It needs to be utf8mb4 to accept characters outside the base plane. I know there is a thread on this somewhere, but I can't find it right now.

The thread I was thinking of is https://gitlab.com/mailman/hyperkitty/-/issues/248
