When I make the request like this:
(drakma:http-request "http://www.w3.org/2001/06/utf-8-test/UTF-8-demo.html")

It results in error:

"<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\"

    the character with code 8254 cannot be encoded.

Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
0: [OUTPUT-NOTHING] Skip output of this character.
1: [ABORT         ] Exit debugger, returning to top level.

Is it some parameter that I forgot to call http-request with to make it aware of utf-8 encoding?

Thank you,
Andrew
