I am going to *GUESS* that those are NON-ASCII characters and that the $XX stuff you are seeing if dBase's way of representing non-ASCII.
But that is not the only problem, as I can see by looking at that dump.
I *think* you need to find a copy of dBase that is localized to your language. It looks to me like the version you have there is for ASCII/English and is not working right for your language. Sorry, but I have no idea how to change those codes in MySQL, once they are imported wrongly.
