Problem with FTP upload weather station data

[scaram...@gmail.com]

I am installing a new server at my station, always made with raspberry and weewx, but I do not suffer to overcome a problem: I can not load the data on my public site and as soon as I activate the service I am returned this error:

No it's the first station I prepare... maybe the twentieth... but it's the first time I've stopped at this problem.... moment of personal stupidity.
The only difference with the past is that the operating system is raspbian bullseye
I don't understand.

Grazie

This has come up before. The problem is that your FTP server is returning results using the 'latin-1' encoding, instead of the far more common 'utf-8'.

The fix is to set option ftp_encoding in the [[FTP]] section.

[[FTP]]

    # (Other options as before)

    ftp_encoding = latin-1

I had read, from the guide on weewx.com, that you could change the encoding of the characters with latin-1, but I did not take into account the need to change coding because I already have several other weather stations that publish on the same server and with the same encoding.
Thank you immensely Tom for the help
