I have identified a couple of problems associated to Unicode, but I can not
debug completely the one you mention.

The terminal is opened using a simple encoding :LATIN-1. It has to be
changed to a diferent encoding in order to allow I/O of asiatic characters

(EXT:STREAM-EXTERNAL-FORMAT-SET *standard-input* ....)
(EXT:STREAM-EXTERNAL-FORMAT-SET *standard-output* ....)

where the "..." is a keyword naming the actual locale that you suspect is
the correct one.

I am unsure about the appropriate choice of encoding for a Windows terminal.
In older experiments it seemed to me that Windows does not use UTF-8. It
would be nice if you could help us identify whether this is the case using
some simple program, such as

(loop for i = (read-byte *standard-input*) do (print i))

and seeing whether your CJK characters are actually UTF-8 encoded in the
terminal or not. Then you may experiment with STREAM-EXTERNAL-FORMAT-SET to
find out the right encoding among the many that ECL supports.
