message-idna problem

[Katsumi Yamaoka <yamaoka@jpl.org>]

Hi,

When I send a mail containing the From header like

From: 山岡 克美 <yamaoka@jpl.org>

the *Messages* buffer collects the following warnings:

Unknown symbol: 山
Unknown symbol: 岡
Unknown symbol: 克
Unknown symbol: 美

I've never noticed this since I rarely use Japanese names in the
message header.  It arises if `message-use-idna' is non-nil and
there is a name of which the first letter is a non-ASCII character
in the header.

Those warnings are the ones that `ietf-drums-parse-addresses'
(a.k.a. `mail-header-parse-addresses') that
`message-idna-to-ascii-rhs-1' uses issues.  Assuming there will
potentially be non-ASCII names when `message-idna-to-ascii-rhs-1'
runs, how about using `mail-extract-address-components' rather
than an ietf-drums- function that does not support non-ASCII
characters?  This problem might not cause a real harm, though.
