Agreed. This was the case when the server sent 
text/html;charset=Windows-1250.

It works fine with -assume_charset=windows-1250. 

I tried -assume_charset=ISO-8859-2, which didn't work, ISO-8859-1 was
assumed, so I wrote that -assume_charset doesn't work.. After some
experiments I found out that the -assume charset flag works only when the
Display and Assumed charsets differ. If they don't, ISO-8859-1 is assumed.
Was this meant to be so?

I don't agree with you here. If the sysadmins don't set there anything
reasonable, the users won't be able to read the documents with right
accents (because the documents aren't marked etc.). They aren't able to
read cyrillic/chinese/hebrew/whatever by now anyway (we don't have the
fonts etc), so it wouldn't limit them any more than they are limited now -
it would just help them to see the documents in Eastern european (read: 
local) encodings..

Well.. I don't think so. I use the -assume_charset flag to override the
assumption that the document is in ISO-8859-1, because of the many
unmarked documents that are in ISO-8859-2 or Windows-1250. Why this
shouldn't work when the assumed charset is the same as my display Charset?

Who wouldn't be. :-)

OK, it works fine with -assume_local_charset.

BTW, why not to set -assume_local_charset to the one we got by
-assume_charset? Do we even need a local charset in this stage, when
without correct local_charset we don't have right "global" documents?
