[Urwid] [PATCH] fix meta utf8 characters

[Nuutti Kotivuori]

Hi,

I recently started toying around the urwid library and I happened to
encounter a bug.

If the terminal is in UTF-8 mode and I input a keybind consisting of
meta and some non-ASCII character, urwid fails with an exception like
this:

,----
|   File "/var/lib/python-support/python2.4/urwid/raw_display.py", line 244, in get_input
|     keys, raw = self._get_input( self.max_wait )
|   File "/var/lib/python-support/python2.4/urwid/raw_display.py", line 299, in _get_input
|     run, keys = escape.process_keyqueue(keys, more_fn)
|   File "/var/lib/python-support/python2.4/urwid/escape.py", line 283, in process_keyqueue
|     return ['meta '+run[0]]+run[1:], keys
| TypeError: can only concatenate list (not "unicode") to list
`----

This is fixed by the simple patch:

I guess this is what was originally meant - it will make the
keypresses be returned as u'meta \xa7', for example.
