Ruby Geokit invalid trailing UTF-8 octet at line 1 column 1 fix

Today I've encountered a small problem with Geokit:

Geokit::Geocoders::IpGeocoder.do_geocode('31.174.47.24')
Psych::SyntaxError: (<unknown>): invalid trailing UTF-8 octet at line 1 column 1

I don't have time (because it happened on production) to investigate this issue, so I've developed a quick temporary fix, which just removes invalid characters:

# Temporary workaround for crazy not UTF-8 characters in response
module Geokit
  module Geocoders
    class IpGeocoder
      require 'iconv'

      def self.parse_body(body)
        yaml = YAML.load(Iconv.conv('ASCII//IGNORE', 'UTF8', body))
        res = GeoLoc.new
        res.provider = 'hostip'
        res.city, res.state = yaml['City'].split(', ')
        country, res.country_code = yaml['Country'].split(' (')
        res.lat = yaml['Latitude']
        res.lng = yaml['Longitude']
        res.country_code.chop!
        res.success = !(res.city =~ /\(.+\)/)
        res
      end
    end
  end
end

Invalid byte sequence in US-ASCII (ArgumentError) with Ruby on Rails

Lately when starting Unicorn instances, I've encountered following issue:

$ bundle exec unicorn_rails -c config/unicorn.rb -E production -D
/gems_path/lib/bundler.rb:294:in `block in load_gemspec_uncached':

There are two ways to fix this. You can export language settings to your shell:

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8

or you can put this into your Gemfile:

if RUBY_VERSION =~ /1.9/
  Encoding.default_external = Encoding::UTF_8
  Encoding.default_internal = Encoding::UTF_8
end

Both methods should work.
