  Choosing simplified chinese in isolinux menu causes corrupted
  characters and untranslated installer

Bug description:
  When booting an oneiric ISO, if you interrupt the initial
  isolinux/syslinux menu, you can select a language.  Selecting
  simplified chinese adds locale=zh_CN to the kernel command line of the
  boot option you select.

  Selecting the second option (install ubuntu) gives the appearance that
  the installer has preselected simplified chinese for the language.  If
  you don't make any changes on the language screen, later on in the
  installer you will find several areas that are not showing
  translations.

  Additionally (and arguably worse), the resultant install has parts of
  the OS that don't render properly such as the date and time indicator.
  Corrupted text is displayed instead.

  Observing /etc/default/locale from an install like this, you'll see
  that LANG is filled out with zh_CN rather than zh_CN.UTF-8.

  $ cat /etc/default/locale
  LANG="zh_CN"
  LANGUAGE="zh_CN:"
  LC_MESSAGES="zh_CN.UTF-8"
  LC_CTYPE="zh_CN.UTF-8"
  LC_COLLATE="zh_CN.UTF-8"

  If you perform an install without making any selections in that
  isolinux/syslinux menu, but instead choose simplified chinese in the
  first language screen, /etc/default/locale will look like this:

  $ cat /etc/default/locale
  LANG="zh_CN.UTF-8"
  LANGUAGE="zh_CN:zh"
  LC_MESSAGES="zh_CN.UTF-8"
  LC_CTYPE="zh_CN.UTF-8"
  LC_COLLATE="zh_CN.UTF-8"

  The logs attached to this bug are from a system that was installed
  with the simplified chinese selected in the isolinux/syslinux menu.
