Problem Note 42092: MINGUO format does not handle 3-digit year properly for widths 7 and 9
The MINGUOw. format uses a base year of 1911. Starting on January 1, 2011, three digits are used to represent the year.  
In the case of MINGUO7. and MINGUO9., there is room for a third year digit, but instead '**' appears in the year field.
