WinSCP supports that (though it cannot be configured in GUI, you would have to set it in registry). Though this can work for downloads only, not for uploads (how do you restore the original character?), so it is useless for synchronization.

Of course translation will be one way only.
It would work for me, as I am in this case interested in syncing from a FTP server (a harddisk recorder).
It is not obvious how to handle implement this.
Any hints how to configure this? (Is there a registry description somewhere other than the code?)

If I can convince my wife, using Replace is probably the way to go.

However "Synchronize Browsing" does not work.

This issue has been added to tracker.

My specific issue is that files on the FTP server have colon ":" in filenames. WinSCP works better than other SW I have tried for this issue, but is not perfect.

* Replace filename unchecked
This is what I would like to use (replacing invalid characters with _), better compatibility with other SW, better readability for transfered files.
Synchronize does not work as described here:
https://winscp.net/forum/viewtopic.php?t=2452

* Replace filename checked
This works for transfering files and directories (I had some issue initially but I cannot reproduce).
However "Synchronize Browsing" does not work.
