Even if you do something like this, even if you manage to figure out
a way to deal with characters that *do not exist* in the US-ASCII
character set (yeah, I can see that konwert may have some limited
capabilities of approximating them, but that sounds quite weird to me);
even if you manage to do that, you will not have the original message.
If you feed the modified message to procmail and it stashes it into some
mailbox/folder/whatever or passes it to another program, you will *not*
have the message that the sender wanted you to have. In some cases this
might not be so bad ("I don't care if a spam message has an extra quote
or not"), but in others, like verifying OpenPGP or S/MIME signatures,
it might be, how do I put it, bad :)

G'luck,
Peter
