Please try Ruby 1.9.2-p136.

Also, report the issue back to win32utils developers:

http://rubyforge.org/projects/win32utils

Who will tell you the same thing, try Ruby 1.9.2

SOLUTION!!!!

Finally, I modified the eventlog.rb with the following lines:

val = buf[56..-1] #--

               if !val.ascii_only?
                val.force_encoding($>.external_encoding ||
Encoding.default_external)
               end
               event_source = val.nstrip
               #puts event_source

newval = buf[56 + event_source.length + 1..-1]

               if !newval.ascii_only?
                newval.force_encoding($>.external_encoding ||
Encoding.default_external)
               end

First your script needs to be in the same encoding that eventlog is
expecting.

As I mentioned, please report this error/bug to win32utils developers
in the provided link, they might be able to help you better.

You mean adding at the top of the script the following line.

# encoding: UTF-8
