Just wanted to report back some experimental results on this. I sent
the following email to both my DoCoMo FOMA D903i and my AU WIN W41H
phones:

The body of the email reads:
=====

This came through perfectly on the DoCoMo, but I got 文字化け on the AU.

Curt, this is precisely why sticking with Shit_JIS for both web and
email is the only reasonable thing to do, outside detecting each
handset and handling it appropriately.

You claim that AU *should* handle UTF-8 in email, and I certainly
believe you, but here is at least one (corner?) case where it does not
work.
