Validation 'alpha' problem

Hi. I am using form_validation at one input. I set the rule alpha. But also this blocks Turkish characters at this input. What should i do? Form validation thinks the Turkish characters are not alphabetical.

Thanks. 

I think you have no other choice but to validate your string with a regex. You can use the regex_match rule, or even better, create a custom rule
