def self.scrub(s)
  # We have a string in UTF-8 with possible invalid byte sequences. It turns
  # out that String#encode can remove these sequences when given appropriate
  # options, but just converting into UTF-8 would be a no-op. So let's convert
  # into UTF-16 (which has the same character set as UTF-8) and back.

  s.dup.force_encoding("UTF-8").encode("UTF-16", invalid: :replace).encode("UTF-8")
