+/**\r
+ Internal function to print a formatted Unicode string to a graphics console device specified by\r
+ ConsoleOutputHandle defined in the EFI_SYSTEM_TABLE at the given (X,Y) coordinates.\r
+\r
+ This function prints a formatted Unicode string to the graphics console device\r
+ specified by ConsoleOutputHandle in EFI_SYSTEM_TABLE and returns the number of\r
+ Unicode characters printed. The EFI_HII_FONT_PROTOCOL is used to convert the\r
+ string to a bitmap using the glyphs registered with the\r
+ HII database. No wrapping is performed, so any portions of the string the fall\r
+ outside the active display region will not be displayed.\r
+\r
+ If a graphics console device is not associated with the ConsoleOutputHandle\r
+ defined in the EFI_SYSTEM_TABLE then no string is printed, and 0 is returned.\r
+ If the EFI_HII_FONT_PROTOCOL is not present in the handle database, then no\r
+ string is printed, and 0 is returned.\r
+\r
+ @param PointX X coordinate to print the string.\r
+ @param PointY Y coordinate to print the string.\r
+ @param Foreground The foreground color of the string being printed. This is\r
+ an optional parameter that may be NULL. If it is NULL,\r
+ then the foreground color of the current ConOut device\r
+ in the EFI_SYSTEM_TABLE is used.\r
+ @param Background The background color of the string being printed. This is\r
+ an optional parameter that may be NULL. If it is NULL,\r
+ then the background color of the current ConOut device\r
+ in the EFI_SYSTEM_TABLE is used.\r
+ @param Buffer Null-terminated Unicode formatted string.\r
+ @param PrintNum The number of Unicode formatted string to be printed.\r
+\r
+ @return Number of Unicode Characters printed. Zero means no any character\r
+ displayed successfully.\r
