Impossible to keep polish signs with a dataport

Hello all, I have created on a Polish database dataport to import a txt file. The character set in the txt file is ISO-8859-2 The problem is that when I import the file, I cannot keep the polish signs. I have used a program to convert data from ANSI to ASCII but it does not cover the need with the Polish set of character. Does anyone (Polish NSC ?) have a program to convert data when importing the txt file so that I can keep Polish signs and accent. Thank for answering me because I really don’t know how to solve the problem. Best regards Arnaud Bultel ATOS ORIGIN France
