Hi all. I have these for my rules in form_validation.php
trim|required|max_length[30]|xss_clean|alpha_dash
I do not want the users to enter any potentially harmful characters so i set the alpha_dash rule. However, all non-English characters ended up being regarded as harmful characters as well. How can i allow the user to enter any non-English character and still prevent stuff like /*-%&#" from being entered?

You would have to make new rules that allowed them.

When using a framework, often people forget that it is built upon an underlying language: if you do not find what you need inside CI then look into PHP itself:
