base OpenPGP with armoring is deprecated. This is *not* the case.

With all due respect, OpenPGP with armoring gets you into all kinds  
of hell as soon as you want to sign more than just us-ascii text,  
and as soon as you want to verify the signature on a system  
different from the one the signature was created on.  This is, in  
particular, the case when users have to feed PGP with a recoded 
version of the message.  Such recoding may be necessary in order to 
properly display the message to you.

Here's a test - this message is encoded in utf-8, it's clearsigned,  
and here is a number of special characters: € ä ö ü æ ç

Using widespread Windows software, can you find a messaging program 
which (1) verifies the signature AND (2) correctly displays the 
special characters (Euro symbol, a-umlaut, o-umlaut, u-umlaut, ae 
ligature, c-cedilla)?  Please tell us.

If you can come up with wording that says MIME is great, but so is 
armoring, send it and I'll look at it.

How about this?

        Note: A specification for using MIME to encapsulate OpenPGP  
        signed or encrypted messages, and for signing and encrypting 
        complex MIME objects with OpenPGP, can be found in RFC 3156.

I'll send a separate message with somewhat more on the character
set issues later today.
