Bug#680932: file-roller: bad encoding as file-roller used 7z instead of 7za when decompressing zip files made under MacOSX

[Mahendra TALLUR]

Package: file-roller
Version: 3.4.2-1
Severity: normal

Dear Maintainer,

this bug occurs when decompressing zip files made under MacOSX (latest version), which contain some UTF-8 characters. For instance, it occurs with a ZIP file containing japanese characters made under a French OSX installation, which is in turn extracted under my system (French locale, up to date Wheezy).

What is important, is that, encoding is detected properly when using 7za from the commandline or when using unzip, but not when using 7z, which is summoned by file-roller by default as of today.

The bad encoding both affects the file listing in file-roller itself, and the resulting files after extracting the archive. I exchanged a couple of emails with the p7zip maintainer who indicated that the behaviour is expected from 7z. 

Would it be possible to depend on 7za instead of 7a ? Would there be some unforeseen consequences ? I think it's quite important for a stable release, as there are quite a few people using OSX likely to make .zip files with UTF-8 characters.

Best regards and thanks a lot for reading and all your work !
