Similar bug to FTPServer-61 found using passwords with not-utf8 characters
--------------------------------------------------------------------------
Key: FTPSERVER-283
URL: https://issues.apache.org/jira/browse/FTPSERVER-283
Project: FtpServer
Issue Type: Bug
Components: Core
Environment: AIX 5.3 64 bit
Reporter: salahzar stenvaag
When specifying a password (PASS command) with special characters like spanish
cedilla we found malformed input exception (see after).
A very similar error has been reported in the past using filenames with special
characters
==>FTPServer-61<==
but the jira had been dismissed because it was assumed (if I understood
correctly) that client libraries should have specified UTF8 encoding, but if we
are using standard clients it is very difficult... As I saw from
http://ftp-software-review.toptenreviews.com/ only smartftp is able to specify
utf-8 for transferring files...
Wouldn't it be possible to patch ftpserver to handle commands channel without
incurring in such nasty low level exception, and decode them using a list of
configurable encodings (utf8, if it fails ISO-8859-2 and so on)?
Or some tricks to use standard clients letting them specify utf8?
Thanks for any hint you can offer to this.
