FTP error on Quit command
I'm using a ftp library that causes an error sending the quit command. It seems that the character before QUIT is not recognized. I took a look at the code but didn't find anything.

Does anyone know what this character can be?
You can probably use a network sniffer to monitor the traffic over the FTP port (21) and check what is the actual character (typically in Hex format).
