imran ansari updated VFS-857:
-----------------------------
Description:
FTPClient method listFiles() fails if the FTP Server contains a file with name
in non-ascii Unicode character. This is mainly reported if the server is
{*}Microsoft IIS based{*}.
VFS2 is not sending "OPTS UTF8 true" in the request for list files.
The following code does not have any effect in case the FTP Server is IIS.
{code:java}
confBuilder.setControlEncoding(options, StandardCharsets.UTF_8.displayName());
confBuilder.setAutodetectUtf8(options, Boolean.TRUE);
confBuilder.setFileType(options, FtpFileType.BINARY);{code}
