Hi David,

Using a Gnome terminal and the default character set "Current Local
Ansi_X3.4-1968" all the asian characters are bad.  Using "Unicode
(UTF-8)" all look good.  So cat'ing _does_ work properly.

On the plus side, being able to display correctly in (1) a Gnome
terminal and (2) in Eclipse's source code window (which uses
"Monospace") and (3) in a Claws-Mail window indicates that all needed
fonts are available.

On the minus side, e experiments to change emacs' mule encoding to
ascii, chinese, and utf-8 don't seem to have any effect :-<

And in an emacs *shell* window (with "mule...set UTF-8", the strings
show up like:

   String sh = "zh: \344\270\226\347\225u"\345\245\275";

which interprets as the octal codes corresponding to UTF-8 char.
