// GxFont_GFX_Example : example to show the use of additional fonts rendering these fonts
//
// Author : J-M Zingg
//
// Version : see library.properties
//
// License: GNU GENERAL PUBLIC LICENSE V3, see LICENSE
//
// Library: https://github.com/ZinggJM/GxEPD
//
// NOTE: you need to SAVE the modified example to a saveable location for UTF-8 characters to work
// e.g. for Umlauts
// for use of additional fonts you need to enable these in file GxFont_GFX.h
// and install the library
//
// selection of the additional fonts is done by the following methods:
//
// void setFont(const uint8_t *font); // selects rendering and fonts from library U8G2_FOR_ADAFRUIT_GFX
//
// void setFreeFont(const GFXfont *f = NULL); // selects rendering and fonts from library GxFont_GFX_TFT_eSPI
// void void setTextFont(uint8_t font); // selects rendering and fonts from library GxFont_GFX_TFT_eSPI
//
// void setFont(uint8_t f); // selects rendering and fonts from library Adafruit_tfGFX
// (no additional fonts, as all are now part of Adafruit_GFX, but fonts above 7bit character set)
//
// void setFont(const GFXfont *f = NULL); // reverts back to Adafruit_GFX FreeFonts
// use setFont((void*)NULL); // to select Adafruit_GFX classic font
//
// these additions may not work with AVR Arduinos
//
// these additions are only partially tested; more tests and additions may follow
