I need user defined characters for my Project.
I live in Germany - we have special alphabetic Characters.
Exampel : ä,ö,ü,ß, centigrade "°" and more.
My Questions: is there an Extension or a new Library  (I2C Modus) ?
Can you help my ?
Thanks for your Support und many Greetings from Germany.

  Hi,
  
  The NHD-0420CW-XXX displays include 3 built in font tables.
  Many of the German characters are located in the built in "ROM B" font table listed on page 18 of the US2066 datasheet.
  
  Each font table can be selected with the "Function Selection B" command listed on page 9 of the US2066 datasheet.
  https://support.newhavendisplay.com/hc/en-us/articles/4414485495703--US2066 
  
  Any characters not listed in the 3 font tables can be created in CGRAM as custom fonts.
  Please see our latest YouTube tutorial on using CGRAM to create custom fonts.
