module EscapeHtmlHelper
  # From now on, CGI#escapeHTML escapes single quotes `'` as `'`, in addition to other supported HTML entities.
  #   This may cause some problems with existing implementations of HTML escaping, in case they do not use
  #   CGI#escapeHTML internally or conform to the established OWASP standard. Therefore, we bring back the old
  #   behavior in form of a helper function, so we can reliably compare actual values with expected ones.
