Summary: Gem win32-eventlog v0.5.2 on Ruby 1.9.1 and 1.9.2

Initial Comment:
1.Requirement:  Read the latest lines of the Windows Application Event
Viewer to verify deployment status executions.
2. Environment: Ruby 1.9.1 On Windows
                win32-eventlog (0.5.2)
                windows-api (0.4.0)
                windows-pr (1.1.3)
3. Problem: On Ruby 1.8.7 my scripts using win32 evenlog api works fine
but on ruby 1.9.1 they don't. I know the String management has changed
on Ruby 1.9.1 and above.

4. Exception Details.
   C:/Ruby191/lib/ruby/gems/1.9.1/gems/win32-eventlog-0.5.2/lib/win32/eventlog.rb:14:in
`[]': invalid byte sequence in US-ASCII (ArgumentError)
        from
C:/Ruby191/lib/ruby/gems/1.9.1/gems/win32-eventlog-0.5.2/lib/win32/eventlog.rb:14:in
`nstrip'
        from
C:/Ruby191/lib/ruby/gems/1.9.1/gems/win32-eventlog-0.5.2/lib/win32/eventlog.rb:613:in
`read'
        from bw_logutil.rb:49:in `read_event_log'
        from bw_logutil.rb:97:in `block in <main>'
        from bw_logutil.rb:96:in `each'
        from bw_logutil.rb:96:in `<main>'
5. Source of Information :
   http://raa.ruby-lang.org/project/win32-eventlog/
6. Tried Solutions.  Tried to use WMI but there is no way to filter the
latest results.

By the way I already use Ruby 1.9.2 and i have the same results.

Could someone help me with this.
