I'll have to agree with Pedro.

Say the user ID should not accept spaces or special characters, so you code something to block all spaces and special characters of standard languages.

That will work until you get a Chinese user. Your database is not prepared to accept unicode data and there you go, your application just broke.

Now, if you coded in the first place to accept only [a-z], [A-Z] and [0-9] characters, the chances to fail that validation would disappear.

So yes, there is a difference between allowing the valid and disallowing the invalid. It has a different perspective. Even worse, imagine having to take into account all alphabets from all cultures.
