This problem happens with Jsch-0.1.34 and Jsch-0.1.31
(I did not check other versions).
Given a remote UNIX directory with an '?' or '*' in its name,
for instance /parent/a?b
Even if the path name is quoted ("/parent/a\\?b"), calling
ChannelSftp.ls(quotedDir) does not return the contents of
dir, but it returns the list of file which reside in
parent/ and match the pattern a?b.
The reason for this problem is that
ChannelSftp.isPattern()
just checks for occurrence of the characters '?' and '*',
but does not check whether these characters have been quoted
with a \ or not.
A slightly related problem to this is that unquoting of
path names is done in the encoded byte[] array rather
than the Unicode String. Given remote path names that
are encoded in UTF-8 or similar, there can be characters
encoded as 2 or three bytes. It's possible that byte
#2 or byte #3 happen to look like a '?' or '*' character,
but are actually not.
Therefore, the unquoting must happen in the Unicode string
rather than the encoded byte[] array -- Util.unquote()
must use String.toCharArray() and work on that one,
rather than String.getBytes().
