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

This program is a test application for testing the actual terminal
emulation only.  If you wish to see gnome-terminal getting this feature
(beware, it's a bit hairy, don't break your system, make a backup,
blahblahblah, standard disclaimer, and if anything goes wrong and gnome-
terminal doesn't start up, just open an xterm to fix things)...

You can either:

- Upgrade to Trusty (with Saucy the story is more complicated: there's
another patch you'd have to apply), download vte-0.34.9 (the exact vte
version that's shipped by Ubuntu Trusty), manually figure out how to
apply the patch (it doesn't apply automatically, requires C coding
knowledge), run ./configure --prefix=/usr
--libexecdir=/usr/lib/libvte-2.90-9; make; sudo make install; and then
quit all instances of gnome-terminal and restart it

Or (this is the one I'd recommend, it'll give you a much newer gnome-
terminal):

- Take vte-0.37.2, run configure with the same flags as above, make,
sudo make install (note: your old vte and vte-0.37 will co-exist on your
system and your gnome-terminal will still use the old version), and then
download gnome-terminal-3.13.2, ./configure --enable-distro-packaging
--prefix=/usr --libexecdir=/usr/lib/gnome-terminal; make; sudo make
install; quit all gnome-terminal instances. In case anything goes wrong,
re-install the gnome-terminal and gnome-terminal-data Ubuntu packages.

Or (the lazy approach):

- Wait for Ubuntu V.V. (15.04) that will hopefully ship this feature.

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.
