Sorting items by names do not work properly

Works normally for me. Can anyone else reproduce this?

Maybe it's because I'm in French language, I can't test here in English (this computer is my brother's one and I can't use it enough)

Yes, I can reproduce this. Sorting doesn't work properly. I use Ubuntu 12.04 64-bit.

It always fails when there is a dash involved. Then Ubuntu uses a totally messed up sorting system. In the following example, Ubuntu sorts according to the character that comes after the dash, but ignoring the previous character(s).

For instance:

Samurai I.txt
Samurai II.txt
Samurai III.txt

Now add a dash and characters following after the dash.
Then Ubuntu will scramble the order:

Samurai II-Duel.txt
Samurai III-Duel.txt
Samurai I-Musashi.txt

Ubuntu now orders according to the words "Duel" and "Musashi" instead of first keeping the sorting of the preceeding "I", "II" and "III". If you use a period "." instead, then the sorting is correct. But if a dash is involved, then Ubuntu fails to sort properly.

See screenshot attached.

Status changed to 'Confirmed' because the bug affects multiple users.

By the way, I use English Ubuntu (US-English). But I have German keyboard setting. Don't know if that has any effect. Just mentioning it, because the original thread starter is on a French system and the other guy said he doesn't have this problem.

Update:

I just found out that it also fails without the dash.

It will still sort like this:

Samurai II Duel.txt
Samurai III Duel.txt
Samurai I Musashi.txt

So obviously the problem is with I, II, III followed by a space character. Obviously the space character has priority before a real letter character. Ubuntu fails completely to do basic sorting. Only if you add "." after I, II, III, only then it sorts properly. It's a mystery to me. Such basic thing should work. I hope this gets fixed. Because this tiny thing makes Ubuntu very hard for me to do effective work when confronted with messed up sorting of my daily files.

Thanks Kevin, I can't confirm that issue on a french locale here ... do you get that if you create a new directory with some files named "2012 - 01.txt" "2012 - 02.txt" "2011 - 06.txt"?

Lisa, your issue seems a different one and similar to some previously reported bugs like bug #322271 or https://bugzilla.gnome.org/show_bug.cgi?id=355152

I created a new folder TEST on my desktop, with files named 2011 - 06.txt to 2012 - 03.txt, it ordered it well. I renamed them by deleting the "space" ("2011 - 06.txt" becoming "2011-06.txt") for each file, it works too.

I verified in the original folder of the bug, it's still buggy, but these one are pdf files (except the other folder, it's the only difference I see)

I confirm this bug. Attached screenshot (folder only with files in it) shows this.

I can reproduce a similar orde issue.

Example:

2012040X
20100506
20100709

After two years a basic error like this must be fixed ...

I have similar issues but with folders as shown in image. 01 folder should come first but does not. It does show first in terminal but not in Nautilus.

I'm running 14.04.3 64 Bit with the following locale settings.
`
LANG=en_US.UTF-8
LANGUAGE=en_US
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"

LC_MONETARY="en_US.UTF-8"

I'm having this problem right now. Ubuntu 15.10, Nautilus 3.14.2. Any sort order I pick in the preferences does nothing in Icon View. I have a desktop where this is not an issue, and I don't know what's different about the two.

same issue, ubuntu 14.04, nautilus 3.10.1, fr_FR.UTF-8 for all LC_***.
I tested with LC_COLLATE=C or POSIX : the behaviour is slightly different, but I can't get a true classic alphanumeric sorting.

Would it be possible to implement a checkbox option on the Nautilus Preferences menu, in order to select :
- keeping the "intelligent (or not so) nautilus sorting type"
- use a regular alphanumeric sorting.

That would be so great.
I a m not used to the collaborative nautilus developpment, so where can I post this feature demand ?
Thanks
