I believe that all three do accept UTF-8-encoded e-mail; certainly
DoCoMo does. Generally it's translated at a gateway, so you don't need
to worry about what the phone supports.

I belive not an issue, since the content is transcoded at a gateway.

It still is with DoCoMo phones, at least MOVA phones, anyway. They allow
longer messages only by splitting the incoming message into several
parts, and sending them as separate messages to the phone.
