vendor/campaignmonitor/createsend-php/class/serialisation.php:38 Function utf8_encode() is deprecated

[wesyah234]

Trying with php 8.2, I received the above deprecation message. Other than that, adding and deleting subscribers worked fine.

Yeah i get this too, im admin currently stays in debug mode, so this is an issue for me. Ive even tried converting the strings to UTF-8 before i give them to CM, still errors.

Change line 38 of serialisation.php from
$v = utf8_encode($v);
to
$v = mb_convert_encoding($v, 'UTF-8', 'ISO-8859-1');

Thanks. I just looked and there are 11 open pull requests on this repo, going back to 2016, the 2 most recent ones both providing the above fix for the serialisation.php file, submitted in June 2023 and November 2023. Is it safe to say Campaign Monitor has abandoned this library? I sure hope not!
