unrar-nonfree does not recognise windows cp1250 encoding

[VladimirCZ]

Binary package hint: file-roller

Recognition of windows cp1250 encoding fails at archives compressed under MS Windows into .zip or .rar format of compressed container, but works well with .7z archives.

Examples attached:
1) Latina.7z ... compressed with the latest 7-zip software under MS Windows XP SP3
2) Latina.zip ... compressed with the latest 7-zip software under MS Windows XP SP3
3) Latina.rar ... compressed with WinRar 2.5 (no unicode support) software under MS Windows XP SP3
The file-roller for
1) 7z: works well
2) zip: extraction done properly, but accented characters are replaced with "?"
2) rar: extraction produces unusable files, when there is an accented character in the path or in the filename of such files.

Detected under:
Ubuntu 9.04 64-bit with non-free unrar installed.

That isn't a file-roller bug. For me, the zip file works perfectly ok in file-roller. The rar file fails in the way that you describe, but also fails when running unrar-nonfree from the command line too.

Hello Chris,
Thank you for sorting out this problem.
Let me ask you about the performance with the ".zip " file:
Have you made some special settings that could effect recognition of encoding of ".zip" files?
Because what I see and get after extraction is on the attached screen-shot.

This is a problem only because the package installs the unrar 32 bit in ubuntu 64bit.

I tested the unrar 64bit downloaded from the official site and I had no problem.

My script to install rar and unrar 64bit in attachment

I have tried the script, installed the 64bit version, tried to uncompress the Latina.rar file and still the same problem with unrecognised characters. So I returned to my previous install.

How can you expect magic happens when the archive itself doesn't support Unicode?

You can run 7-zip or WinRAR with wine, though.
Given proper locale environmental variables passed to wine, archivers on behaves exactly same as that of Windows.

For the zip issue, check bug 1199239

For the rar issue, non-Unicode rar archives are very rare now.
If you encounter, you may use unar [1] to decompress them.
