Different usage patterns?  Do  you often cut&paste text between Emacs,
xterm and Mozilla?  I do it very very very often.

I  could be,  but I'd  say  it's unlikely.   Emacs quite  consistently
behave  like  that,  whether   I'm  using  xterm,  Mozilla,  Netscape,
GTK-based  things, etc.   And the  other apps  simply  cut&paste among
themselves happily without problems.  Emacs is the odd man here.

And I would  assume that xterm has been  programmed correctly, because
it's such a classical apps. that is so heavily used.  Perhaps I should
try also 'xedit', which uses the classical Athena widget set, which is
a sort  of "reference" implementation  of an application using  X, Xt,
Athena and X11.

I seldom cut&paste non-English  non-ASCII non-text stuff between xterm
and Emacs.  I'm sure that 99%  of the time that I encounter this Emacs
misbehaviour,  I'm  trying  to  cut&paste purely  ASCII  text.   URL's
(already URL-encoded) being a non-negligible portion of it.

Unlikely.  See above.

Too bad that they don't follow the "standard".

But I've  tried also (set-clipboard-coding-system  'utf8).  It doesn't
work    with    Mozilla     when    I    cut&paste    Chinese    text.
(set-clipboard-coding-system  'iso-8859-1) does  make  Emacs cut&paste
German text from Emacs properly.  But  most of the time, I leave Emacs
with its default (i.e. using 'ctext' for the cut&paste).

I  think xterm  always  uses SELECTION.   xterm  doesn't even  support
Unicode, let alone UTF-8.
