ftp program used in Poland?

A friend of mine told me that his filezilla FTP program corrupted the Polish language characters when he downloaded from his site. He wants to buy a program that is commonly used in Poland. What program should he buy? How about Ipswitch? Does anybody have experience with this?

Thanks!

Problem exists between keyboard and chair.

I think your reply is really funny and probably very 'Polish.'

Are you saying then that there is no problem and that ANY FTP program will work?

Thanks

any properly written- yes, will work.
