I have a file named foobarë. When I try to 7zip it on Debian (stable) via Putty, I get the following:

server:/tmp#  7za a test.7zip foobarë

7-Zip (A) 9.04 beta  Copyright (c) 1999-2009 Igor Pavlov  2009-05-30
p7zip Version 9.04 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,1 CPU)

foobarë:  WARNING: No more files

Creating archive test.7zip

WARNINGS for files:

foobarë : No more files
WARNING: Cannot find 1 file

Somewhere along the way the foobarë is converted to foobarë. How can I fix this?

My locale on Debian (at least, the content of /etc/locale.gen and locale -a) is en_US.UTF-8 UTF-8.

Make sure PuTTY is in UTF-8 mode. Go to Window → Translation, under Remote character set choose UTF-8. Go back to Session, select Default Settings and click Save.

It may be that the version of 7-Zip you are using is an old version and if I remember correcly around the 9.04 area there were two versions of 7-zip, one which used the standard character set and another that was Unicode.

The current version of 7-zip is 9.20, yours appears to be 9.04. Can you update and try again?

There is also a bug report from the p7zip (Unix port of 7-zip) Sourceforge page that claims this was fixed since 9.13, so again I would recommend updating to 9.20 if possible: Sourceforge Bugtracker

The answer might also be in Putty... Putty itself (Window->Translation) wasn't set to UTF-8. I've switchted to UTF-8 now, my foobarë file now has a weird name, when I make it again it 7zips correctly.
