Jens M Kofoed commented on NIFI-10143:
--------------------------------------
[~pgrey] I have made some more test.
Testing with windows built in command line ftp. After connecting to the ftp
server I see this: "200 OPTS UTF8 command successful - UTF8 encoding now ON"
Testing different scenario with non-english words works fine with danish
charecters. With my currently selected character set, I can't see arabic
characters in the command prompt, but FTP are still able to handle files with
Arabic characters, and upload them just fine.
So it seems like MS FTP are handling utf8 just fine. But I still have issues
with NIFI accessing MS FTP. But it seems like NIFI don't have issue with
FileZilla FTP Server. So where the different is, I don't know.
Unfortunately we are not able to switch to FileZilla FTP Server since it does
not support MS-AD and NTFS rights
> ListFTP/GetFTP has issues with danish special characters (UTF-8)

> Environment: NIFI Version 1.16.2, Java 8
> Reporter: Jens M Kofoed
> Assignee: Paul Grey
> Priority: Major
>
> ListFTP and GetFTP has issues listing file/directories including danish
> charaters (æøå).
> The ftp server is MS IIS FTP, and UTF-8 has been set to true.
> with a small test flow, I used a GenerateFlowfile and added 2 Properties.
> filename="test.txt" and path="æøå". The output is going to a PutFTP, with
> Remote path set to ${path}
> The PutFTP does indeed create a subfolder at the ftp server, named æøå. But...
> With a ListFTP or GetFTP process, looking into the same root folder gives an
> error.
