change c2 font

found on the s9 forum:

Rename your True Type font file(.TTF) into USER.TTF, and
copy to the SYSTEM folder. Select USER FONT from the
menu to apply to the device.

Certain types of USER FONT may not be properly shown.
It also may delay the device operation. Certain USER FONT
types may not work properly in multi languages.

(georgia looks quite nice)
