819 * xr Use roman numerals for the next numeric format character
820 * xh Use hebrew numerals for the next numeric format character
821 * xx Literal x
822 * xg Genitive month name
823 *
824 * xij j (day number) in Iranian calendar
825 * xiF F (month name) in Iranian calendar
826 * xin n (month number) in Iranian calendar
827 * xiY Y (full year) in Iranian calendar

832 * xjx xg (genitive month name) in Hebrew calendar
833 * xjn n (month number) in Hebrew calendar
834 * xjY Y (full year) in Hebrew calendar
835 *
836 * xmj j (day number) in Hijri calendar
837 * xmF F (month name) in Hijri calendar
838 * xmn n (month number) in Hijri calendar
839 * xmY Y (full year) in Hijri calendar
840 *
841 * xkY Y (full year) in Thai solar calendar. Months and days are
842 * identical to the Gregorian calendar
843 * xoY Y (full year) in Minguo calendar or Juche year.
844 * Months and days are identical to the
845 * Gregorian calendar
846 * xtY Y (full year) in Japanese nengo. Months and days are

851 * literal quotes. Example:
852 *
853 * "The month is" F => The month is January
854 * i's" => 20'11"
