[Bug 1297051] Re: gnome-terminal doesn't recognise C1 controls

[Egmont Koblinger]

I figured out it works in xterm and putty with ISO-8859-x charsets, just
not with UTF-8.

Title:
  gnome-terminal doesn't recognise C1 controls

Status in “vte3” package in Ubuntu:
  New

Bug description:
  gnome-terminal seems not to recognise the C1 control characters.

  The particular character that is a problem for me is CSI. However
  there may be a generic issue with non-support of this whole range of
  characters.

  This range of characters should only be recognised when the encoding
  is a character set that is defined to include the C1 control
  characters but, at a quick look, that is all of the ISO-8859-x
  character sets and Unicode. (C1 control characters require encoding as
  a 2 byte sequence when the encoding is UTF-8. As unlikely as this may
  be to occur in practice, UTF-8 is not inconsistent with C1 control
  characters.)

  Part of the motivation for raising this bug report is that PuTTY seems
  to have declined in reliability recently and so I looked at why I am
  using PuTTY as opposed to gnome-terminal. Correct support of C1
  control characters is one reason. This works in PuTTY. It does not
  appear to work in gnome-terminal. Perhaps resources would be better
  spent making gnome-terminal work as well as PuTTY does, rather than
  attempting to get PuTTY fixed.
