I am using WinSCP on my desktop computer, with two monitors, in my home office. WinSCP is connected to a virtual machine guest running on the same host system. In order to use my desktop while sitting with my kids in the living room, I connected from a laptop to the desktop via TeamViewer. While the TeamViewer connection was active, I updated TeamViewer on the laptop (which automatically disconnected and reconnected itself).

My desktop had sat idle for a few hours, with WinSCP running, before I started TeamViewer, and I didn't look at WinSCP until a bit after TeamViewer updated itself, and after doing some web browsing, at which point I brought WinSCP to focus and discovered the error prompt. I *assume* the error occurred while TeamViewer was updating, as that might have done something wonky with enabling/disabling windows.

WinSCP 5.21.3

Stack trace:

The problem happens rarely. I cannot reproduce it.

I have the interface in Explorer mode. When I open a remote directory that contains a file with a german umlaut-u ('ü', Unicode code point 0xFC) in its name, the session abruptly closes with this error message:
When I click abort, I get another error message:
When I click OK there, sometimes (not always), this error message shows up:
I can click "Reconnect" in these dialogs but it never works. I just get the same error message again. I can also not manually connect to this device, since WinSCP will try to open that same directory again, which causes the same error.
I need to completely close the session tab, open the "Advanced Site Settings" -> Environment -> Directories, and change the "Remote directory" under "Remember last used directory".

In "Advanced Site Settings" -> Environment -> Server environment, "UTF-8 encoding for filenames is currently set to "On", but this also happens when it is set to "Auto" or "Off".

WinSCP 5.19.5
Just to be thorough, I updated to WinSCP 5.21.3 (current version at the moment) and it still happens.
It also happens with other non-ASCII characters.

The remote device is a custom embedded device running a Buildroot Linux. Using FileZilla to connect to it and enumerate the files in that directory works fine, so I don't think it's a server-side issue.

The log file has this error on line 519:
It's very easy to get confused by the encodings here, so I'll spell it out very explicitly: The log-file seems to be properly encoded in UTF-8, since, when decoded with UTF-8, other non-ASCII text comes out readable (e.g. "Mitteleuropäische Zeit").
The log file, at that quoted location, contains the bytes , which, when decoded with UTF-8 like the rest of the file, comes out to be these Unicode-code-points (in hexadecimal) with the characters corresponding to those code-points above them for easier orientation:
Which looks like the byte-sequence produced by encoding the text 'ü.txt' with the 1252 encoding. But, of course, this is not supposed to be a byte-sequence, since it's already decoded. A sequence of bytes and a sequence of Unicode-code-points is not the same thing. The code-points just happen to all be below 256.
You might already understand this well, but I wanted to explain it thoroughly, just to avoid confusion.

I wrote a program to check possible ways this text could have been mangled and it found these combinations:

So it seems there is a really nasty encoding bug somewhere.

My thoughts:
* According to https://winscp.net/eng/docs/faq_utf8#sftp and https://winscp.net/eng/docs/ui_login_environment#utf, WinSCP should automagically not use UTF-8 when the server sends non-UTF-8 file names, but, as explained above, the problem also persists when the "Use UTF-8" option is set to "Off".
* In FileZilla I can select "Force UTF-8" and it still works fine. On the other hand, when I force it to use the 1252 encoding, the file names come out mangled (in this case, "ü.txt" is displayed as the file name, which matches the "ü.txt" -[UTF-8]-> ... -[1252]-> "ü.txt" pattern). This further indicates that the server is properly sending file names encoded with UTF-8.
* The error messages says "cannot encode local path name", as opposed to decode. This could be a typo, but if we assume that it isn't, the problem didn't occur while decoding the byte-sequence sent from the server, but while encoding something. I am not sure what this would be. But the surrounding log messages suggest that it did happen while processing incoming data. Not sure what to make of this.

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

The problem happens rarely. I cannot reproduce it.

I had 5 sessions opened, some on VMs.
From a PuTTY command line on the host OS I killed a guest OS virtual machine that had an open session in WinSCP.
I accidentally clicked on a the "dead" tab instead of the X to close it. WinSCP froze for a while then this error report option popped up.
