Dear dev team I've created this issue: https://issues.apache.org/jira/browse/NIFI-10143 Some might argue that this is a Microsoft issue, since I can get it to work with FileZilla Server. But after an older patch/update to NIFI ( https://issues.apache.org/jira/browse/NIFI-8250) the utf8 issues worked with MS as well.
But it seems that after an newer update ( https://github.com/apache/nifi/commit/95abc35463d43ea9ee62dc041f85dca38579fec2) the FTP class has been totally rewritten, and now it doesn't work any more. FTPPut can upload and create files/folders with non-English characters, but List/GetFTP can't finde them. MS says the folder names are ???? instead for non-English characters. After making some changes to MS, to include UTF8 in the whole system, and not only for the FTP, List/GetFTP can get non-English characters file. But PutFTP can't create folders with non-English characters any more. kind regards Jens
