I am asking you Mark if that is why you don't have the issue here, but we have the latest version of Moo Buk and we had this issue. The programmer added a fix today.
If your site only installed latin languages, you can hot fix by removing line "encoding" => "utf8" in \app\Config\config.php . After this line is removed, you can use emojis on your smartphones.
That is why I had to close, the sections, topics and blogs
It seemed very ugly, writing an article, half the words appeared as emojis depending on how many parentheses there were
