Good catch, it is indeed the case.

you can reproduce this bug by editing /etc/passwd, adding some accented
letter to some user's full name, :set fileencoding=latin1 and save.

Then ohai will indeed fail like that. It will also fail with LANG=C
LC_ALL=C.

$ LANG=C LC_ALL=C ohai
/usr/lib/ruby/1.8/json/common.rb:232:in `to_json': source sequence is 
illegal/malformed (JSON::GeneratorError)
        from /usr/lib/ruby/1.8/json/common.rb:232:in `pretty_generate'
        from /usr/lib/ruby/1.8/ohai/system.rb:222:in `json_pretty_print'
        from /usr/lib/ruby/1.8/ohai/application.rb:104:in `run_application'
        from /usr/lib/ruby/1.8/ohai/application.rb:75:in `run'
        from /usr/bin/ohai:47


Ciao,
