Answer 1

~ UPDATE ~

ruby-iconv has been superseded from Ruby 1.9.3 onwards by the encode method. See Jörg W Mittag's answer for details, but in short:

utf8string = "èàòppè"
iso_string = utf8string.encode('ISO-8859-1')

I agree with Williham Totlandt in thinking that this type of conversion might not be the smartest idea ever, but anyway: use ruby-iconv :)

utf8string = "èàòppè"
iso_string = Iconv.conv 'iso8859-1', 'UTF-8', utf8string
