Geoff,
Nicely put together test case. I was able to reproduce your outcome closely
(different FTP server).
What made it work for me was the following change to the VFS source:
Index: FtpClientFactory.java
===================================================================
--- FtpClientFactory.java (revision 1535203)
+++ FtpClientFactory.java (working copy)
@@ -150,7 +150,11 @@
{
client.setControlEncoding(controlEncoding);
}
-
+ else
+ {
+ client.setAutodetectUTF8(true);
+ }
+
client.connect(hostname, port);
final int reply = client.getReplyCode();
… and then not specify any encoding in the test code. I don't know whether this
is the right thing to do in general, but it made all your test cases succeed
for me.
