Emails and charset issue

[Pierrick Brossin]

Hi!

Is there a way to make sure my mail client is really using UTF-8 as
charset ?
Headers claims so but people reports I'm not

X-Newsreader: Sylpheed version 0.9.4 (GTK+ 1.2.10;
i386-portbld-freebsd5.1) Content-Type: text/plain; charset=UTF-8

I'm not a charset guru but I assume there's nothing to install on both
side to make it work except the mail client :)

Could anyone tell me the way to make sure or confirm I'm really
using UTF-8 ?

Thanks
