(Package hint: unrar)
Well, it's non-free but open source software.
Download http://www.rarlab.com/rar/unrarsrc-4.2.4.tar.gz
And check the license statement inside.

(Package hint: unrar-free)
There is a true free version that support legacy RAR archive version
only. But virtually no one use it. File Roller pulls unrar and
ubuntu-restricted-extras has dependency unrar.
http://packages.ubuntu.com/raring/ubuntu-restricted-extras

The tricky thing is, if the user install ubuntu-restricted-extras
during installation or on a fresh system, everything looks fine.

If she trust File Roller's Search Command, then rar would be
automatically pulled and UTF-8 file name / path then break.

I never assume every user is savvy on package management or  well
informed on the situation of RAR issue.

rar package is a trial version of closed source RAR archiver anyway.
As long as we ship it, ship a sane version rather stuck on a beta
version for several cycles.
