Problem with search resaults in Polish language

I have a problem with Opencart - Version 1.4.9.2

When I use polish national characters in search field - there are no results. When I search without polish national character everything is ok - search works great.

Have you got any idea how to fix it?

Which file (i need patch) generates search resaults and where is SQL query responsable for generating search resaults?

Thank you for help in advance.

Pete

I have got the same problem on newest Version 1.4.9.3!

Please - help me with this issue.

Hi:

Search at catalog/model/catalog/product

functions: getTotalProductsByKeyword() and getProductsByKeyword()

perhaps: add to sql search string the: COLLATE utf8_unicode_ci

Best,

Hilde
