I just installed the Tapatalk plugin on my vBulletin 3.x forum and got the iOS app working. Everything seems mostly good so far but I noticed a strange problem: when posting from the iOS app, all apostrophes are turned into question marks. This happens for all users with the app. Here's an example: https://nas-row.com/showpost.php?p=12121&postcount=234
Any idea how to fix this? I assume that it's a string scrubbing function designed to prevent SQL injection or something. Maybe it can convert to HTML character escape instead?
Found a reference to this problem on another site. Looks like it's a regression introduced by iOS 11?
