To be candid, it was little bit beyond my comprehension;-(
Especially "yta/rg==" and "AC1/" parts were puzzling to me.
But if you are concerned with mixing up of 2-byte Japanese chars and
1-byte ASCII chars in matching operation, then it is not necessary.
EUC Japanese chars could co-exist with ASCII chars "safely"
and any byte of EUC char would not be mis-interpreted as ASCII char.
That is a reason I need to convert to EUC code system before manipulating
internet mails which is transmitted in another code system.
FYI, mails change to yet another splendid code system on my PC!
Sounds exciting?:-)

Thanks.
Actually, I want to use this $HENSHIN matching to delete
quoted portion in reply message from cc:Mail such as
from
____________________________ HeNsHiN ________________________________
to the end of mail.
Does
sed -e '/^_* $HENSHIN _*$/,$d'
work?
So far, I have received only Japanese cc:Mail message with such portion.
To prepare for domestic cc:Mail message with quotation,
could anyone tell me the corresponding word in domestic cc:Mail?
Is it "Reply"? "REPLY"? "Quote"? Or?
TIA.
