For mere documentation purposes, please note that if the server is a Windows 
IIS FTP server, UTF8 will not be used in connections even if it is allowed in 
server configuration, unless explicitly specified. This is even if FTPClient's 
{{controlEncoding}} is set to {{UTF-8}}.

So Chinese/Japanese characters will be returned as question marks ({{?}}) 
unless an {{"OPTS UTF8 ON"}} command is issued after connecting.

This should work as long as the control encoding is set appropriately. 

Remember that the printstream encoding and txt encoding for your ide/terminal 
must also be set. Tthe following works for me:

{code:java}  
   FTPClient client = new FTPClient();
   client.setControlEncoding("utf-8");
   client.addProtocolCommandListener(new PrintCommandListener(new 
PrintWriter(System.out)));
   client.connect("localhost");
   client.login("user", "pass");
   
   PrintStream out = new PrintStream(System.out, true, "utf-8");

   for (FTPFile file  : client.listFiles())
   out.println(file.getName());
   
   
   out.println("你好吗"); // this filename was printed in the test above
{code}
