When I set the alpha validation rule for a input field in my form and when I type characters like ŠĐČĆŽ etc the rule doesn’t see those characters as letters. I use a database that has UTF-8 encoding. How do I modify the regex ( “/^([a-z])+$/i” ) to include those letters?

EDIT: I can do it with “/(*UTF8)^([a-zšđčćž])+$/i” . Is there a better solution?

Create a callback rule, the already included ‘alpha’ rule is only supposed to work with latin characters (and next version will use ctype_alpha() instead of a regular expression).

Thank you for answering. For now I just extended the Form_validation class (added MY_ prefix etc).

Btw can you give me a link where I can find future changes (like the one you just written about ctype_alpha() being used in the next version).
