Subject: Re: String.strip with UTF-8

it made a difference, but I can see it's not a space now which explains
why it didn't strip

Loading development environment (Rails 3.0.3)
ruby-1.9.2-p136 :001 > d = Domain.last
 => #<Domain id: 2055, classification: "Internationalized Country Code 
Top Level Domain", dns_name: "xn--mgbaam7a8h", idn_name: "امارات.",
