Categories w/ accents not displaying products

-- HikaShop version -- : 2.3.0
-- Joomla version -- : 3.3.6
-- PHP version -- : 5.4.33

Hello,

The problem we're having when browsing categorie listings is if a category has accent, like for instance "Toucas de Natação" (the 'ç' and the 'ã') then not products are shown when that categorie is selected.
I tried adding an alias to this products that does not contain accents (e.g. "Acessorios" as alias for "Acessórios") and that solves it.

Then i tried adding aliases with accented characters (like "Acessórios1" or even "Acessórios") and it keeps working OK. That's because when I hit the save button the Alias is automatically converting converted to the non accented spelling ("Acessórios1" -> "Acessorios"). Then i tried removing the alias and it still works, that's because when hitting the save button the alias is automaticly created from the name with accented characters converted to non accented.

So the real problem was that this categories had not been saved.
How they came to be created with no alias automaticly created is probably due to this being a J3.3 site with the Hikashop categories and products imported from VM in a J1.5 Site (so Hikashop omport from VM in J1.5 and then in J3.3 we imported the Hikashop J1.5 tables)

PS: of course the problem only happened with SEF URLs enabled

Hikashop is a great product. This is a bit of a lenghty post but i just wanted to share in case someone has the same problem.

Regards
