>Description:


xterm-259 from pkgsrc X has the following problem:


If you
  - start it in non-utf-8 mode
  - switch to utf-8 mode with the ctrl-rightmouse menu
  - do some stuff
  - switch back to normal mode with the ctrl-rightmouse menu


then only output handling and not input handling switches back away
from utf-8. That is, if you print characters 128-255 from programs,
they're displayed as the matching iso-latin-1 glyphs; but if you paste
characters 128-255 into the xterm they are converted to utf-8 on the
way in and programs read them as multibyte sequences. This conversion
is apparently enabled when utf-8 mode is switched on, but not disabled
again when it's switched off.




>How-To-Repeat:


prepare something suitable in your cut buffer, open a fresh xterm, and
paste into cat as follows:


	% cat | hexdump -C
	<correct glyph>
	00000000  d8 0a                                             |..|
	00000002


switch on utf-8 mode:


	% cat | hexdump -C
	<correct glyph>
	00000000  c3 98 0a                                          |...|
	00000003


switch off utf-8 mode:


	% cat | hexdump -C
	<wrong glyph>
	00000000  c3 98 0a                                          |...|
	00000003


>Fix:


	dunno, probably obvious if you know where to look, which I don't.
