title: gsub ASCII code characters from a string in ruby
body: <p>I am using nokogiri to screen scrape some HTML.  In some occurrences, I am getting some weird characters back, I have tracked down the ASCII code for these characters with the following code:</p>
  
  <pre><code>  @parser.leads[0].phone_numbers[0].each_byte  do |c|
      puts "char=#{c}"
    end
  </code></pre>
  
  <p>The characters in question have an ASCII code of 194 and 160.</p>
  
  <p>I want to somehow strip these characters out while parsing. </p>
  
  <p>I have tried the following code but it does not work.</p>
  
  <pre><code>@parser.leads[0].phone_numbers[0].gsub(/160.chr/,'').gsub(/194.chr/,'')
  </code></pre>
  
  <p>Can anyone tell me how to achieve this?</p>
