Zen cart 1.3.9h - easy populate addon fix a problem while importing a txt (csv format)

I have zen cart 1.3.9h and a programmer altered the free easy populate addon for my store. My store and my database is all in UTF-8 unicode because it is English and in Greek language. The addon works properly when you export all products from my database but it does not work properly if i try to import or alter products in my store that have a category name written with Greek letters - this category and its subcategories does not appear correctly in my store. The same time the same product uploads properly its english category and subcategory. If you have a problem with Greek letters and you can not see them then i guess you can try with a different language than english that requires special UTF-8 characters like the Greek language. I will provide you access to our test server that has everything installed After you fix this bug then i will need you to add some new product fields from my database to the easy populate addon. I am will to give up to 40$ for this small fix (i am saying it is a small fix because if you know what you are doing it must be something really easy for you)
