Fixed Data portability : error on export when UTF8MB4 chars (emojis in username) [Invalid Character Error in src/XF/Service/User/Export.php at line 42]

Affected version

2.0.7

Hello,

When a username is containing emojis in it's username, and I export the user with the new data portability feature, it is throwing the following error :

DOMException: Invalid Character Error in src/XF/Service/User/Export.php at line 42

1. DOMDocument->createElement() in src/XF/Service/User/Export.php at line 42
2. XF\Service\User\Export->exportEntry() in src/XF/Service/AbstractXmlExport.php at line 38

I just got the same error while trying to export a member who also has an emoji in his username.

I don't see to have an issue generating XML files containing emoji:

<?xml version="1.0" encoding="utf-8"?>
<data_portability_user>
  <user username="Chris 🤪"

I guess it could be related to PHP version, which version are you guys running?

Either way, we'll just strip the emoji here to be safe.
