Random Question Marks (?) Appearing in Posts

I'm running Xenforo v2.2.2.

Recently, random ? characters are showing in posts.

Here's a link to one thread.

Appreciate any help.

I do not have anything set up in the Censor area to change anything to a question mark.

Is it an incorrectly parsed Emoji?

Have you ever had to restore your database from a backup or from a mysql dump?

Sorry. You likely have an ip address in a range that I blocked because of spammers.

Maybe. I could ask members what they were trying to post.

Yes, but that was years ago, and not recently, and this just started.

In one of the replies (#20) the user mentions it happens with emojis.

It turns out that it is emojis that are native to a mobile device.
