UTF-8 filenames in SCP mode?

2010-05-14 00:31

When you configure WinSCP to work in SCP mode, it do not allow you to enable UTF-8 filenames on remote side.
It is a bug or intended (mis)feature?

Far2 x86, if that matters.

And how to read non-ASCII file names then?

I vote for this feature. I believe, WinSCP should be transformed from ACSII to Unicode version for that (which is a bit of work)? Otherwise remote folder contents should be in the charset compatible with FAR console charset (no way to display Chinese on Cyrillic). I am right?

Pity that full Unicode support is in WinSCP since 5.0, but FAR manager users cannot benefit from this.

nope. WinSCP 5.0.2 beta does not support Unicode encoding in SCP mode.

Here's hope that once 5.0 is out, the FAR manager plugin could get some love as well.

Does anyone have a success for filename Unicode encoding in SCP mode with WinSCP 5.0.2 beta?

It's strange that when I use ssh@cygwin to login the server, all filenames are decoded correctly, but winscp can't.

alternative to winscp?

Here is a list of ssh clients:
https://en.wikipedia.org/wiki/Comparison_of_SSH_clients

But I am not sure which one support scp and filename utf-8 encoding/decoding.

found "UTF-8 is not supported with SCP protocol." here: https://winscp.net/eng/docs/ui_login_environment

DropBear can transport UTF-8 encode filenames in scp,but remote panel display it in ansi.
when use sshd as host,in scp mode,the remote panel always display filenames in ansi encoding too.
can i change this default encoding to UTF-8?

using scp connection to a server with LANG=de_DE.UTF-8

using scp connection to a server with LANG=de_DE.UTF-8 did not use UTF-8 coding for filenames.
no way to choose the right character set with winscp?

winscp-version is 5.5.6 built 4746

wrong documentation about a feature that does not work?

2015-01-29 17:50

I think the information on https://winscp.net/eng/docs/ui_login_environment#utf is wrong.
utf-8 did not work in winscp with a scp-connection either LANG is set on the remote site to UTF-8 or not.
Is it allowed to change the wrong information there? Or will it work as described sooner or later?

As documented, UTF-8 is supported with SCP protocol in the latest beta release only. Please upgrade.
See https://winscp.net/tracker/325

latest beta version

2015-01-30 21:36

Thank you for your hint! Although utf-8 is set (LANG=de_DE.uft-8) the last beta version did not use UTF-8 if option AUTO is set. But there is an option to change to utf-8 manually and after changing the option utf-8 is used.

Thanks for your report.
Please attach a full log file showing the problem (using the latest version of WinSCP).

To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

I created a login file, but I don´t think there is any hint for debugging in it.
The "UTF-8 encoding for filenames" was set to "On". If it is set to "Auto" it did not work.

Thanks, but this is a log for "On". I need a log for "Auto".

Thanks for the log:

There's no UTF-8.
Maybe you set the LANG to "UTF-8" for interactive sessions only.

Maybe - but i´m not sure, where to change the environment settings for non-interactive shells. Is it /etc/profile.d/ or better /etc/ssh/sshd_config or better to create a user specific ~/.ssh/environment?
I can´t identify the file where LANG=de_DE@euro may be set.

It varies. Try .bashrc (instead of .bash_profile).

Do you use PuTTY? What is value of LANG, when you login with PuTTY with Connection > SSH > TTY > Don't allocate a pseudo terminal turned off?

Normally "Don't allocate a pseudo terminal" is off and the result of set|grep LANG is
LANG=de_DE.UTF-8
LANGUAGE=de_DE:en
If i activate the button before connecting i cant enter enything (no bash?)

Well, I'm not an expert on *nix shell environment. But clearly, as you can see, WinSCP behaves correctly, based on the information it gets from your server.
