//  Created by Bodmer 24th Jan 2017

// The latest Arduino IDE versions support UTF-8 encoding of Unicode characters
// within sketches:
// https://playground.arduino.cc/Code/UTF-8

/*
  The library expects strings to be in UTF-8 encoded format:
  https://www.fileformat.info/info/unicode/utf8.htm

  Creating varaibles needs to be done with care when using character arrays:
  char c = 'µ';          // Wrong
  char bad[4] = "5µA";   // Wrong
  char good[] = "5µA";   // Good
  String okay = "5µA";   // Good

  This is because UTF-8 characters outside the basic Latin set occupy more than
  1 byte per character! A 16 bit Unicode character occupies 3 bytes!

*/

//  The fonts are stored in arrays within the sketch tabs.

//  A processing sketch to create new fonts can be found in the Tools folder of TFT_eSPI
//  https://github.com/Bodmer/TFT_eSPI/tree/master/Tools/Create_Smooth_Font/Create_font
