This blog was running on the beautiful Aegea. But in the latest version (Version 2.7, build 3254) at the time it lacked one feature we can't imagine our life today - emojis 🙂

When you try creating or updating a post with some nice 👻 they will be both shown and saved to the database as '?' (question marks).

Until there is an official fix, here's a hacky solution. I spent a whole day going through obfuscated code, so you won't have to. 🙂
In core.php apply these changes:

1. Change
   >$w8e815='utf8';

• to
  $w8e815='utf8mb4';

2. And remove this line:
   $e1cb25=rff7c($e1cb25);

If the changes above won't help, try adding this in /etc/mysql/my.cnf and restarting mysql:

[client]
default-character-set = utf8mb4

[mysql]
default-character-set = utf8mb4

[mysqld]
character_set_server=utf8mb4
collation_server=utf8mb4_unicode_ci

In case you're wondering on which stack this does work - I'm on php 7.0, nginx 1.10.3, mysql 5.7.22, ubuntu 16.04.

Happy blogging! 😎
