gedit can't open a txt file

[Simplehuman]

I have a txt file with a list of pages of different sites (related to my work). It is generated by Firefox plugin "Webmaster Sape".
When I try to open it with gedit I see an error message: "Unknown error: Invalid byte sequence in conversion input".

But for ex. Geany and LibreOffice Writer open it without any problems.

File is attached.

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

Just upgraded to Quantal a week ago. Used gedit to edit a text file this morning and it worked fine. Restarted my computer and then tried to edit the same file again and got "Unexpected error: Invalid byte sequence in conversion input."

There shouldn't be any strange characters in the file.

[Matt White (mfwhite5)]

Bizarre workaround for this bug: cat the file from the command line and then copy and paste it back into a new text file in gedit. I had to copy-paste-save it in sections, because if I pasted the entire document into gedit all at once, the invalid byte sequence error remained.

I am continuing to get this error on files that used to be able to be opened by gEdit. Here's an error message that is logged relating to this:

** (gedit:13182): WARNING **: Hit unhandled case 1 (Invalid byte sequence in conversion input) in parse_error.

I’ve been facing a similar issue. For me the problem was that the encoding of the file had changed since it was last opened with Gedit (from WINDOWS-1252 to UTF-8). As I had manually set the encoding when first opening the file, Gedit had saved this information and tried to reuse it the next time I opened the file after the encoding change; this resulted in said error message.

To fix the problem, I had to remove the saved encoding information from the gvfs metadata like so:

    gvfs-set-attribute --type unset MY_FILE.txt 'metadata::gedit-encoding'

I have posted more information on this at <http://askubuntu.com/a/279820/137449>.

It is still actual, any attention to this bug?

What you attached is not a .txt file, but rather a .tar.gz archive containing a .txt file. After unpacking it Gedit opens it fine:

zcat wmsape-list.txt.tar.gz > wmsape-list.txt.tar
tar xf wmsape-list.txt.tar
gedit wmsape-list.txt

[Sebastien Bacher (seb128)]

the txt is not a text, it's a compress archive rather, that's not a bug

[Simplehuman (simplehuman)]

Yes, it is .tar.gz archive with a .txt file, wich is NOT opening with gEdit, but is opening normally wil another text redactors (Geany, Writer, etc.)
So the bug is not invalid

[Simplehuman (simplehuman)]

I'm attaching this txt file without compression...

sorry, I misunderstood the previous comment, that's a duplicate of bug #575500 then
