I can at least explain the error you're getting: when you edit any page,
MediaWiki includes a hidden form field with the text 'ℳ𝒲♥𝓊𝓃𝒾𝒸ℴ𝒹ℯ'
in the edit form. If this value doesn't arrive when you submit the form,
it displays that error and prevents you from saving the edit to avoid
corrupting pages. The error assumes your browser corrupted that text,
but I guess it's also possible that your server or configuration might
do it…
That's interesting.
I believe there is also a setting in LocalSettings.php that allows one
to set the character set for the database. This was my first guess:
$wgDBTableOptions = "ENGINE=InnoDB CHARSET=utf8";
