qtubuntu sends wrong text as part of QKeyEvent

[Albert Astals Cid]

When using Unity7 or Plasma a key event created by Ctrl+C is
  QKeyEvent(KeyPress, Key_C, ControlModifier, text="\u0003")

But Unity8+ qtubuntu send to the application
  QKeyEvent(KeyPress, Key_C, ControlModifier, text="c")

This is most likely because QMirClientInput::dispatchKeyEvent is using xkb_keysym_to_utf8 to get the text of the event instead of using xkb_state_key_get_utf8

This breaks for example Konsole that expects the correct text to be sent.

[Andreas Pokorny (andreas-pokorny)]

Mir either has to expose the xkb_state (which we currently do not - and might be only on the server) or provide the keysym text directly with the event.

[Andreas Pokorny (andreas-pokorny)]

Went for the second approach key entry text is attached to every press and repeat event.

Fix committed into lp:mir at revision None, scheduled for release in mir, milestone 1.0.0

[Daniel d'Andrada (dandrader)]

Alt+Up and Alt+Down to switch between tabs in Kate also doesn't work currently. Could it have the same cause as this Ctrl+C issue?

[Albert Astals Cid (aacid)]

Don't think so, Alt+Up/Alt+Down don't have text attached.

Also http://paste.ubuntu.com/24045824/ seems to report the same presses in both unity7 and unity8
