Problem ftp files with special letters in the file name

I?m testing edtftpnet-1.2.2.dll and it works ok but got into problem to ftp files with Nordics special letters (?, ? ?).

When I try this:
ftpConnection.UploadFile(?d:\temp\V?sj?.jpg?, ?V?rs?.jpg?, false);

Getting this exception:
V?ret_til_sj?s_2009_06_18_12_03.MP3: The filename, directory name, or volume label syntax is incorrect. (code=550)

Any ideas how to make it work ?

Thanks.

You need to set the ControlEncoding property appropriately.
