I'm not sure if it works either, but just to clarify - I think what
Eugene wants, is something like this:

if header :contains "from" "Štěpánek" { ... do whatever ... }

The problem is that headers with non-ascii chars are encoded in form
like this:

Subject: =?UTF-8?B?UmU6I.....gVG9v?=

And also the body is sometimes completely in base64, even though it is
just plaintext or HTML in UTF-8. Depends on sender's mail client.

So the question is whether Cyrus decodes this stuff before checking and
applying the sieve rules.
