Cannot download the file with foreign characters

[Thomas]

Server ftp in UTF8 mode.
The problem is that I have many files with the same foreign char in name (as ą or ł or ć or ż, etc.) but only a few of them (of files) are not able to download.
So when I take such kind of file from "failed transfers" and rename it (get rid of the char from name) and restore back the name (again rename and write the missing char) I'm able to download this file.

IIRC vsftpd supports UTF-8 only in the way that is passes it through to the underlaying filesystem.

How were those files created on the server in the first place?

[Thomas]

Unfortunately, it is difficult to determine because it is not my server (but the problem I meet very often so I was wondering if filezilla does not know a cure for this problem).

How are created ... by different ftp clients, the PHP environment (for example, by joomla) or directly.

[Thomas]

And one important observation, it seems that in an earlier version of FileZilla (2.x), this problem does not occur, like using other ftp clients the problem is not noticeable, there is only in FileZilla 3.x

[Tim Kosse]

This confirms it, those files were almost definitely created using the wrong character set. Please delete them and re-upload them using FileZilla so that the proper encoding is used. In case you delete them using FileZilla, restart it between deletion and reupload.

Ok but why other ftp clinet works well? and the old filezilla also works correctly!

[Tim Kosse]

Pure luck. Those other clients and also the old FileZilla are in violation of the FTP standard. What happens then is purely undefined, anything could happen.
