I am Korean, and files with Korean file names are stored on my ftp. When I connect to my ftp and look up the file list, an error occurs. Please check the attached image.

My NAS is set to UTF-8 encoding. In Android applications, filezilla, and iPhone applications, the FTP file list is normally displayed.(Of course, these applications are also configured to connect to FTP with UTF-8.) However, this only happens with the Freefilesync app.

The strange thing is that in the past freefilesync version 10.1 did not cause any problems. This has been happening since version 10.2 and has not been fixed until now.

Is a fix possible? If necessary, I can open some folders on my NAS for testing. Please let me know if you need it.

I suspect your FTP server is failing to correctly identify UTF8 support via FEAT: https://www.rfc-editor.org/rfc/rfc2640#section-3.2
You can check this e.g. via FileZilla by manually sending the "FEAT" command.

The output is as follows:
Command: FEAT
Response: 211-Features:
Response: MDTM
Response: MFMT
Response: TVFS
Response: MFF modify;UNIX.group;UNIX.mode;
Response: MLST modify*;perm*;size*;type*;unique*;UNIX.group*;UNIX.mode*;UNIX.owner*;
Response: LANG en-US*
Response: REST STREAM
Response: SIZE
Response: 211 End

There is certainly no UTF-8 response. Unfortunately, it is impossible for me to modify this because my NAS is from a specific company (EFMiptime). Is there any way to force a UTF-8 connection?

FFS could auto-detect the server encoding, so let's give this a try:

I'm late to check your reply. Sorry.
I tested the recently updated version and confirmed that it was connected normally. thank you!
