Title:
  localechooser in ubiquity will pick lzh_TW instead of zh_TW when
  timezone set to Taipei

Status in localechooser package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce:
  1. Install Ubuntu, use English as default language but manually set the timezone to Taipei
  2. Boot to desktop, run command `locale`

  Expected Result:
  * You should only see "en_US.UTF-8" and "zh_TW" in the output

  Actual Result:
  * You will see "lzh_TW" instead.

  Impact:
  This will cause error when running commands like apport, which will call the locale.py in Python

  Traceback (most recent call last):
    File "/usr/share/apport/apport-gtk", line 598, in <module>
      app.run_argv()
    File "/usr/lib/python3/dist-packages/apport/ui.py", line 694, in run_argv

      return _parse_localename(localename)
    File "/usr/lib/python3.6/locale.py", line 490, in _parse_localename
      raise ValueError('unknown locale: %s' % localename)
  ValueError: unknown locale: lzh_TW
