Subject: Re: ActiveRecord to_json encoding

Brian, I really appreciate the quick reply and the insight.  Our team 
was contemplating upgrading to Ruby 1.9 for all the new features but 
have concerns with any regression.  Will you tell me why you reccommend 
staying on 1.8.6 for production rather than 1.9?  Also how do you enter 
the accented e on "Caf辿"
in the console (IRB)?

Thanks in advance.
