Do emails that are written in Japanese occupy more disk place on an Exchange
2003 Store than those written in Engilsh?

Probably. Japanese probably uses Unicode, which is two bytes per character,
whereas English can be represented with one byte per character.

Even ASCII text?

Pretty much in all cases, yes. Quickly skimming through KB325621 confirms
that;

If you think that is a waste of space you really don't want to know how some
rule properties are stored in your already limited amount of rules space.
Ok, I'll spoil it; in both Unicode and ASCII format and sometimes even
twice. I'm sure it is done for a good reason though. Probably backwards
compatibility has something to do with it.

No wonder the rules space fills so easily.

Yup, there were quite some scenarios where upgrading to Outlook 2003 caused
rules to be disabled (because they converted as well at that point). I also
came across this while doing some testing for the book I wrote with Sue a
few years back. It deserved a KB article and has been added as a tip (page
294 if you happen to have a copy);

I see the KB has been updated for Outlook 2007 and Exchange 2007 now as well

:-)

Not by definition.
For more info on multilingual support of Exchange, ask in an Exchange
newsgroup.

What makes you think that a Japanese encoded message would take up a
different amount of space than say a European encoded message? Because
double-bytes are used? (This is not a sarcastic question; I am really
curious why you ask this.)
