def decompose(type, codepoints)
  if type == :compatibility
    codepoints.pack("U*").unicode_normalize(:nfkd).codepoints

  end
end

#tidy_bytes(string, force = false) ⇒ Object

Replaces all ISO-8859-1 or CP1252 characters by their UTF-8 equivalent resulting in a valid UTF-8 string.

Passing true will forcibly tidy all bytes, assuming that the string’s encoding is entirely CP1252 or ISO-8859-1.
