def sanitize_file_name(name)
  # NOTE: We could use ActiveSupport::Inflector#transliterate also, but that would remove diacritics also...
  name.gsub! /^.*(\\|\/)/, ''
  name.gsub! /[\:\*\?\"\<\>\|]/, '_'
  name.gsub! "—", "-"
  return name.encode('ISO-8859-1', :invalid => :replace, :undef => :replace, :replace => '_')
