Bug description:
  [SRU Justification]
  Wrong translations and wrong behavior of upgrader

  [Regression potential]
  Code changes are specific to an input function used at one specific point in the upgrader and should be very testable.

  [Test case]
  1. On Ubuntu 14.04, get a root shell in a terminal.
  2. Run 'apt install language-pack-el'
  3. Run 'LANG=el_GR.UTF-8 do-release-upgrade -d'
  4. Confirm that the upgrader is shown in Greek.
  5. When prompted whether or not to upgrade, confirm that the Continue prompt shows 'Συνἑχεια [yN]' instead of the expected 'Συνἑχεια [νΟ]'.
  6. Type 'y<enter>' and see that the input is ignored and the prompt redisplayed.
  7. Hit '<enter>' and see that the input is ignored and the prompt redisplayed.
  8. Type (or cut and paste) 'ν<backspace><enter>' and confirm that the upgrader crashes.
  9. Reset the environment by running sudo mv /etc/apt/sources.list.distUpgrade /etc/apt/sources.list
  10. Run 'LANG=el_GR.UTF-8 do-release-upgrade -p'
  11. Confirm that the upgrader is shown in Greek.
  12. When prompted whether or not to upgrade, confirm that the Continue prompt shows 'Συνἑχεια [νΟ]'.
  13. Type (or cut and paste) 'ν<backspace><enter>' and confirm that the upgrade cancels cleanly.
  14. Run 'LANG=el_GR.UTF-8 do-release-upgrade -p' again.
  15. Confirm that the upgrader is shown in Greek.
  16. Type (or cut and paste) 'ν<enter>' and confirm that the upgrade proceeds.

  I tried `do-release-upgrade -d` on an up to date 14.04 system, with
  Greek locale=el_GR.UTF-8.

  I got notified that some packages are no longer supported by Canonical, and then I got this prompt:
  Continue [yN] λεπτομέρειες [λ]

  λεπτομέρειες means details.

  I tried pressing [λ] and I got the (hopefully attached) crash. If it's
  not attached, I also uploaded it to http://paste.ubuntu.com/15941779/.

  Then it restarted the upgrade process and it got to the same prompt. At that point, [λ] worked and showed me the no-longer supported packages,
  but y/n didn't work at all, so I couldn't continue.

  I pressed Ctrl+C to abort the upgrade process,
  but now `do-release-upgrade -d` tells me there's no new distribution available to upgrade to, possibly because it's checking my just-broken sources.list...
