Hi again Konstantin, please use the unpatched version for the bug
report. That will send it to Emacs maintainers and not here.

Other platforms don't in general use the internal ls-lisp implementation 
to generate dired buffers, and most systems use utf-8 encoding in the 
locale these days, so even if file-attributes is called somewhere else 
with 'string as its second argument, there is a good chance that Emacs 
23 will display the username correctly without decoding.

Also, while trying to test this, adduser refused to work, advising:

adduser: To avoid problems, the username should consist only of
letters, digits, underscores, periods, at signs and dashes, and not 
start with
a dash (as defined by IEEE Std 1003.1-2001).

So the probability of users on other systems running into this bug are 
fairly low.

OK, but the solution should still be general, in `file-attributes',
and it is to decode the string by locale-coding-system, don't you
agree?

Yes, DECODE_SYSTEM should be used here.
