   *   to 'en' if not provided. Warning: this can be unfiltered user input.
   * @param string $unknown_character
   *   (optional) The character to substitute for characters in $string without
   *   transliterated equivalents. Defaults to '?'.

   *   (optional) If provided, return at most this many characters, ensuring
   *   that the transliteration does not split in the middle of an input
   *   character's transliteration.
   *
   * @return string
   *   $string with non-US-ASCII characters transliterated to US-ASCII
   *   characters, and unknown characters replaced with $unknown_character.
