Also I'd like to allow white spaces " " in nicknames (yes, the character you make when you press the spacebar button in your keyboard). No members have liked this post.

Did you read the link? the fact that a-z are allowed means every character between a AND z including a AND z are allowed.
The bold snippet is for foriegn characters.
