Sometimes you want to strip a text of every special char. If you use \W, the result might not be what you wanted:

    irb> "Eine längliche Kristall §$&&%& Lampe über dem Esstisch verschönert jedes noch so kahle   \n  Speisezimmer".gsub(/\W+/, " ")
    => "Eine l ngliche Kristall Lampe ber dem Esstisch versch nert jedes noch so kahle Speisezimmer"

You need to use "[^[:word:]]", which is magically given to us by the spirit of the community Show archive.org snapshot

    irb> "Eine längliche Kristall §$&&%& Lampe über dem Esstisch verschönert jedes noch so kahle   \n  Speisezimmer".gsub(/[^[:word:]]+/, " ")
    => "Eine längliche Kristall Lampe über dem Esstisch verschönert jedes noch so kahle Speisezimmer"
