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

I tried the new version Ruby 1.9.2, installing the win32-eventlog gem
but the same result.

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

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
