Have you guys encountered it and how do you deal with it. Basically CI dev's have hardcoded the added product names to be only latin and the cart doesn't work with cyrillic or special chars and some people say that day have problems with utf8 encoded chars, you can use a hack for the product rules in order to permit cirillyc chars
$this->cart->product_name_rules .="_-а-яА-Я ";
but i have encountered a different problem which is the cart randomly doesn't work for like 5% of the visitors. You can't add anything at all. Some writeups on internet suggest to use
but the major problem that i have is that the bug can't be reprodused in order to see if I have fixed it. I encountered the bug in one of my pc's but the next day everything was working fine, without changing the code.
