Am working on something and it needs usernames to not have any Special Characters. Up until now, I've allowed users to register 'Any Character' in their username.
Now, I want to prevent usernames having space at beginning or end, have at least 2 characters and must not have the following characters: < > \ " ' % ; ( ) &
My questions are:
- Would the setting,
ASCII (no international unicode)* be the best option?
- And, if I set this new setting, how will it affect existing users who have those characters in their usernames?
Take care and keep safe,
*General>User registration settings>Limit username chars: ASCII (no international unicode)
