file-roller doesn't handle zip archives containing accentued characters correctly

[Jonathan Ernst]

Binary package hint: file-roller

Every time someone sends me a zip archive (.zip) with files containing characters like é, è, ç, etc. the following happens :

1) File-roller shows a badly decoded name in its interface
2) Sometimes it's impossible to extract the file because the command line generated by file-roller uses those badly decoded names

Extracting the files with unzip file.zip works perfectly though

Thanks for the report, this is known upstream, you can track it here: https://bugzilla.gnome.org/show_bug.cgi?id=306403

It's not only a Mac OS X problem. If a zip a folder (to a .zip archive) with accents in Ubuntu 10.10, I simply can't extract it or view the files using file-roller. Though the command unzip works perfectly.

Same problem occurs with .rar files.

Using file-roller on Ubuntu Quantal (3.6.1.1).

When I add a file which filename contains "à", this letter is replaced by "??".

As I studied this issue a little bit, I'd give a brief summary here.
There are Unicode enabled and non-Unicode enabled ZIP archives.

If you system has unzip/zip but not 7z, neither type of ZIP archives can be displayed in File Roller. This due to limitation of unzip.
If you system has 7z, File Roller can correctly display Unicode enabled ZIP archives.

For non-Unicode enabled ZIP archives, you can handle them with lsar/unar (included since 12.04), which supports encoding conversion natively.
