[SOLVED] Character encoding conversion

Hi, my first post here...
I'm writing a shell script (using tcl/expect) to show mails on pop server.
How do I convert e-mail headers containing text like this:

Subject: =?iso-8859-1?B?ZGl2ZXJ0aW1lbnRvIHNlbnphIGZpbmUgMjQgb3JlIHN1IDI0?=

to make it readable?
I already tried with 'iconv' and 'recode' with no luck...
Thanks.

Re: [SOLVED] Character encoding conversion

These subjects have (probably unnecessarily) been encoded according to RFC 2047.

The "B" in between the 2nd and 3rd ? indicates that it is encoded using Base64 (if there's a Q it's "Quoted-Printable" see RFC RFC 2045).

So you're looking for a Base64 decoder.

EDIT: and there happens to be one in coreutils. 

man base64
