Issues mirroring files with hi-bit characters in filename

[Brenda]

I'm trying to mirror a site that has files with filenames that contain hi-bit characters in the filename. The files are being saved to a network drive, but I don't see that being an issue.

It works okay in Firefox. This is what firefox reports as the filename :-
ftp://ftp.apple.asimov.net/pub/apple_II/documentation/hardware/video/VDP-1000%20plus%20User%92s%20manual.pdf

This is the error I get from FreeFileSync :-

Error Cannot read file "ftp://ftp.apple.asimov.net/pub/apple_II/documentation/hardware/video/VDP-1000 plus User�s manual.pdf".
CURLE_REMOTE_FILE_NOT_FOUND: RETR response: 550
550 VDP-1000 plus User�s manual.pdf: No such file or directory [curl_easy_perform]

I'm using version 9.8 under Windows 10 x64

thanks
Brenda

Technically, this is data corruption on the server: The ’ character is returned in ANSI encoding, while the server announced to return UTF8, which is what FFS then expects.
