Title:
  Bash in gnome-terminal shows control characters as unsupported-unicode
  squares

Status in gnome-terminal package in Ubuntu:
  Expired

Bug description:
  Binary package hint: gnome-terminal

  When I upgraded to Karmic (clean install) I noticed bash echoes
  control characters using the hat notation (ex. ctrl+c shows as ^C).
  stty reported echoctl being set, so I tried to unset it. This helped,
  and pressing ctrl+c at a prompt cancels the prompt, shows a new one
  and nothing is echoed.

  Though, when pressing ctrl+c while a program is running (ex. cat or
  ping), a unicode square is echoed like for unicode characters not
  supported by the selected font. I tried selecting many different
  encodings and fonts, though nothing seemed to help.

  Futher, if inside this same shell I open a screen session, this
  behaviour is gone and everything works as intended, which is to have
  ctrl+c or ctrl+z have the desired effect with nothing echoed.

  Finally, opening a bash session in xterm or tty[1-6] and disabling
  echoctl/ctrlecho using stty command, this cannot be reproduced. So it
  seems that only an plain bash session in gnome-terminal does this.

  To see a screenshot, view the attached PNG.
  Basically what happens there is
  1. 2 ctrl+c presses at the prompt.
  2. Then 1 ctrl+c during cat
  3. Then 1 ctrl+z during cat
  4. Bring cat back to the foreground and press ctrl+c again
  THEN disable echoctl
  5. Repeat the process - where you can now see instead of hat notation, the prompt presses are fine, but the in-program presses echo unicode squares.

  Very frustrating.
