David Handermann commented on NIFI-10143:
-----------------------------------------
Thanks for reporting this issue [~jmkofoed].
The changes for NIFI-6266 should have maintained support for UTF-8 handling in
the FTPClient through the UTF-8 Encoding property, but the changes moved
property configuration to the StandardFTPClientProvider class:
[https://github.com/apache/nifi/commit/95abc35463d43ea9ee62dc041f85dca38579fec2#diff-815ac6b9740e1a8327479cb5784d20016372250d543c7c5204a31feff659e53fR149]
As you noted, however, it sounds like the new implementation did not maintain
the expected behavior.

> Key: NIFI-10143
> URL: https://issues.apache.org/jira/browse/NIFI-10143
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.16.2
> Environment: NIFI Version 1.16.2, Java 8
> Reporter: Jens M Kofoed
> 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.
> ListFTP[id=e4c43ea1-2d5d-1fea-ffff-ffff89c101ce] Unable to get listing from
> /���; skipping: java.io.IOException: Cannot list files for non-existent
> directory /���
>
> Testing the old case from NIFI-8250. I got issues with the arabic charaters
> too.
> PutFTP[id=e4c43ef3-2d5d-1fea-ffff-ffffea9da690] Unable to transfer
> FlowFile[filename=اختبار] to remote host 192.168.1.2 due to IOException
> thrown from PutFTP[id=e4c43ef3-2d5d-1fea-ffff-ffffea9da690]:
> java.io.IOException: Failed to store file .اختبار to /test/اختبار due to: 550
