Subject: Problem when removing accents from a String

Hi,

I've spend several time trying to replace latin characters in strings.
What I want is something like this:

Given the word "camión", I would like to get the following string:
"camion".

I've found several solutions in the Internet but they only work in the
Rails console, and when I try to launch my Rails application on Mongrel
(I am using Netbeans) nothing is working and from "camión" I am getting
"camin" instead of "camion".

For example, I've tried with these snippets:


1.*********************************
def nice_slug(str)

    accents = {
      ['á','à','â','ä','ã'] => 'a',
      ['Ã','Ä','Â','À','Á'] => 'A',
      ['é','è','ê','ë'] => 'e',
      ['Ë','É','È','Ê'] => 'E',
      ['í','ì','î','ï'] => 'i',
      ['Í','Î','Ì','Ï'] => 'I',
      ['ó','ò','ô','ö','õ'] => 'o',
      ['Õ','Ö','Ô','Ò','Ó'] => 'O',
      ['ú','ù','û','ü'] => 'u',
      ['Ú','Û','Ù','Ü'] => 'U',
      ['ç'] => 'c', ['Ç'] => 'C',
      ['ñ'] => 'n', ['Ñ'] => 'N'
      }
    accents.each do |ac,rep|
      ac.each do |s|
      str = str.gsub(s, rep)
      end
    end
    str = str.gsub(/[^a-zA-Z0-9 ]/,"")

    str = str.gsub(/[ ]+/," ")


    str = str.gsub(/ /,"-")

    str = str.downcase

  end


2.*************************
"camión".parameterize

It throws the following error:

undefined method `normalize' for "cami�n:String

c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.2.2/lib/active_support/inflector.rb:283:in

`parameterize'

3.*************************************
"camión".mb_chars.decompose.scan(/[a-zA-Z0-9]/).join

It throws the following error:

undefined method `decompose' for "cami�n:String


I am using Ruby 1.8.6, Rails 2.2, Mongrel 1.1.5 and Windows XP.


Please, some help.
