Hmmm... not the best example here, ... technically if you are talking
size.  We got too many encodings for Japanese.  You see too many ESC
code for jis-2022.

Our choice of encoding is not much to do with size.  It is inertia and
backward compatibility.


Many Japanese e-mail uses jis-2022 for compatibility.  (E-mail was safe
only for 7 bit data in old days).  

As far as data size goes, compact popular ones are EUC(Unix) or S-JIS(MS
system). These are used in web pages etc. still.  These are as small as
UTF-16/UCS-2 used for many Unicode data internally.

But please note new MAC and XP/Vista/... use Unicode and I see many
files can be in UTF-8.  So things are changing.
