Hi,

For some reason, xt-mouse with xterm-mouse-utf-8 on isn't working for me
under rxvt-unicode. I assume it worked at some point, but it's not
working now.

I investigated it a little and it looks like the (read-char nil nil 0.1)
call is no longer reading an entire UTF-8 character unless the
inherit-input-method argument is non-nil. I don't know why that is.
But, in any case, this patch fixes it for me:

Subject: [PATCH] Fix xterm mouse tracking of high coordinates with
 xterm-mouse-utf-8

read-char now needs inherit-input-method to be non-nil for it to read
a whole UTF-8 code point, even with set-keyboard-coding-system.

* lisp/xt-mouse.el (xterm-mouse--read-coordinate): Call read-char with
inherit-input-method as t.

----------------------------------------------------------------------

Reproducer:

- Run urxvt
- In it, run emacs -Q -nw
- M-: (require 'xt-mouse)
- M-: (setq xterm-mouse-utf-8 t)
- M-x xterm-mouse-mode
- Make sure the window is wider than 96 lines or columns
- Move the mouse around past the 96th line or column

Hope this helps.
