* start with "x":
*
* xn Do not translate digits of the next numeric format character
* xN Toggle raw digit (xn) flag, stays set until explicitly unset
* xr Use roman numerals for the next numeric format character
* xh Use hebrew numerals for the next numeric format character
* xx Literal x
* xg Genitive month name
*
* xij j (day number) in Iranian calendar
* xiF F (month name) in Iranian calendar
* xin n (month number) in Iranian calendar
* xiy y (two digit year) in Iranian calendar
* xiY Y (full year) in Iranian calendar
* xit t (days in month) in Iranian calendar

* xtY Y (full year) in Japanese nengo. Months and days are
