Well, that depends on the CGROM font table in the LCD and how consistent Yamaha was over the years with their specs and procurement. There are certainly characters above 127, but they are an order-able character set from the LCD vendor (or more correctly the HD44780 vendor which is probably Hitachi or other Japanese).
Download the Hitachi data book that has the HD44780 and/or HD44780A (or even the HD44780U LCD-II)? in it. That's your starting point.
