On Debian-Stretch:
$ DEBCONF_SYSTEMRC=1 DEBCONF_NOWARNINGS=yes debconf-show console-setup
  console-setup/fontsize: 11x22
  console-setup/codeset47: # Latin2 - central Europe and Romanian
  console-setup/fontface47: TerminusBold
  console-setup/charmap47: ISO-8859-2
  console-setup/fontsize-fb47: 11x22 (pouze framebuffer)

  console-setup/store_defaults_in_debconf_db: true
  console-setup/codesetcode: Lat2
  console-setup/guess_font:
  console-setup/fontsize-text47: 11x22 (pouze framebuffer)
  console-setup/framebuffer_only:

On Debian-Sid:
$ DEBCONF_SYSTEMRC=1 DEBCONF_NOWARNINGS=yes debconf-show console-setup
  console-setup/guess_font:
  console-setup/codesetcode: Lat2
  console-setup/framebuffer_only:
  console-setup/fontsize-text47: 10x20 (pouze framebuffer)
  console-setup/fontsize-fb47: 10x20 (pouze framebuffer)
  console-setup/charmap47: UTF-8
  console-setup/use_system_font:

  console-setup/codeset47: # Latin2 - central Europe and Romanian
  console-setup/store_defaults_in_debconf_db: true
  console-setup/fontsize: 10x20

On Debian-Jessie (the bug also shows up in Jessie, I was wrong in the report):
$ DEBCONF_SYSTEMRC=1 DEBCONF_NOWARNINGS=yes debconf-show console-setup
  console-setup/fontsize-fb47: 11x22 (pouze framebuffer)
  console-setup/fontface47: TerminusBold
  console-setup/use_system_font:
  console-setup/fontsize-text47: 11x22 (pouze framebuffer)
  console-setup/guess_font:
  console-setup/charmap47: ISO-8859-2
  console-setup/framebuffer_only:
  console-setup/store_defaults_in_debconf_db: true
  console-setup/codeset47: # Latin2 - central Europe and Romanian
  console-setup/fontsize: 11x22
  console-setup/codesetcode: Lat2

On Debian Wheezy:
$ DEBCONF_SYSTEMRC=1 DEBCONF_NOWARNINGS=yes debconf-show console-setup
  console-setup/codeset47: # Latin2 - central Europe and Romanian
  console-setup/framebuffer_only:
  console-setup/guess_font:
  console-setup/store_defaults_in_debconf_db: true
  console-setup/use_system_font:
  console-setup/fontsize: 8x16
  console-setup/fontface47: TerminusBold
  console-setup/fontsize-text47: 8x16
  console-setup/charmap47: ISO-8859-2
  console-setup/codesetcode: Lat2
  console-setup/fontsize-fb47: 8x16



But I think the problem is with the 'keyboard-configuration' package - 
reportbug also queries it when reporting a bug for console-setup and it 
shows some non-ascii characters. The resulting encoding is independent on 
the LANG variable.
