ls bug compairing filenames with certain chars

[ribbonz]

This is probably just an ls bug, but I'm adding a ticket just in case.

Here's the output from Terminal that gives a simple way to produce the error:

~> mkdir tmp
~> cd tmp
~/tmp> touch 'Efigênia'
~/tmp> ll
total 2
-rw-r--r-- 1 user root 0 Oct 30 12:50 Efigênia
~/tmp> touch abc
~/tmp> ll
ls: cannot compare file names 'Efig\303\252nia' and 'abc': Invalid Argument
total 4
-rw-r--r-- 1 user root 0 Oct 30 12:50 Efigênia
-rw-r--r-- 1 user root 0 Oct 30 12:51 abc
~/tmp> ls --version

The "cannot compare file names..." error message came up after I had downloaded a jpeg file that had 'Efigênia' as part of the name.

I'm using a stock alpha3. I don't know if coreutils has been updated since then (I'm guessing not).

What locale are you set to?

What locale? Um... the regular one, I guess. I haven't changed anything.

Preferences::Locale app shows "English" in the Language tab, and "English (United States)" in the Formatting tab. Which works for me, because I speak English and live in the United States. :)

There are several similar tickets (#6263, #7700, #7853) which may have the same cause. So this might be a duplicate.

This is indeed a bug in ls ; if the locale isn't set, it defaults to the POSIX locale and doesn't correctly handle anything non-ascii. This doesn't occur on newer revisions though since we now explicitly set the LC_* variables, which makes things behave a bit better.
