Unwanted control characters

The user input in my website an email address sometimes appears like this and is saved in the database [email protected]Â Â Â Â Â Â Â Â Â Â Â Â or similar. In the resulting printout it is like this [email protected] � I think these are space characters from a non-UTF-8 charset. I have tried using a regex which I am sure is wrong 

$email = preg_replace('/[\t ]/', '', $email);

and I have tried 

$email=trim($email);

Can someone please guide me on this?

Brilliant. The filter did it. I tried the regex but it had no effect. BTW the UTF-8 statement is in the HTML head. I guess that forces it but not sure. I didn't try the urlencode but it is something to remember with future problems.

you can use filter_var($email, FILTER_SANITIZE_EMAIL) to remove all invalid chars or filter_var($email, FILTER_VALIDATE_EMAIL) if you prefer to check the email and warning the user if there is some problem
