The client received an incorrect character encoding from the server. This can happen if the client expects UTF-8 encoding but the server uses a different encoding (code page).
Solution
Go to the Favorite Properties
For FTP connections: Go to the FTP property page For SFTP connections: Go to the SSH - SFTP property page
Set the Code page to the correct code page the server uses or use "Current Windows ANSI Code Page" For example, if the server uses a Latin derived language from Western Europe (Spain, France, Italy, Portugal, etc), set the Code page to 28591 (ISO 8859-1 Latin I)
