In trying out a few new things I did run into a problem in batch mode, because 
(print FOO) can generate improperly encoded output if FOO contains characters 
outside the system locale.  For example, if the file t.el uses UTF-8 encoding 
and contains this:

;; -*- coding: utf-8 -*-
(print "‘x’ “y” `z'")

and Emacs is in an 8-bit locale, the command 'emacs --batch -l t.el' will output 
the string "‘x’ “y” `z'" to stdout in a UTF-8 encoding, which is an encoding 
error for this environment.

Although this problem can occur with any non-ASCII character, diagnostics 
containing curved quotes will make it more likely.  I installed the attached 
patch to fix this, using the same technique for standard output that Emacs is 
already using for standard display.
