Various and sundry character encoding problems.

Upstream ticket: http://dev.ctor.org/soap4r/ticket/503

Just dropping this here. I'm taking a look now, but since the upstream's bug is two years old, I'm not exactly holding
my breath.

Steps to Reproduce:

todb@mazikeen:~/.rvm/gems/ruby-1.9.1-p378/gems/UPnP-1.2.0$ ruby test/test_UPnP_SSDP.rb 

Result:
