XF 2.2 My members always use strange symbols as their usernames

[syqhcc]

What should I do to stop this phenomenon?

In /admin.php?options/groups/usersAndRegistration/ use this option:



That will limit user names to a-z and 0-9 only.

Any existing ones will need to be manually changed.

You might like to add a space in there too as lots of users (like me too) use a 2 part name with a space in between.

Additional characters just need to be included after the 9, like so: /^[a-z0-9 _-]+$/i
