I need to store some data in a MySQL table, but I got some problems with theese kind of characters: "ā" "æ" "ō" "ĕ" (and so on)

Till now I had theese data stored in a SQLlite database and it was great because all was good, but now I'm trying to export it in a MySQL DB, but the strange chars are stored not in the good way, even if I tried different char encode. (UTF-8, UTF-16, latin blah blah)
Does anyone know the correct way to do so?

thanks a lot!!
