显示Unicode字符

官方例程写的很清楚了

需要在/src/utility/In_eSPI_Setup.h的最后加上 "#define USE_M5_FONT_CREATOR"

#include 
#include "CUF_24px.h"

void setup()
{
  M5.begin(); //Init M5Stack.  初始化M5Stack
  M5.Power.begin(); //Init power  初始化电源模块
  M5.Lcd.setFreeFont(&unicode_24px);  //Set the GFX font to use.  设置要使用的GFX字体
  M5.Lcd.setTextDatum(TC_DATUM);  //Set text alignment to center-up alignment. 设置文本对齐方式为居中向上对齐
}

void loop()
{
  M5.Lcd.fillScreen(0);
  M5.Lcd.drawString("Hello world", 160, 60, 1); //Hello world is displayed in font 1 on (1600.60).
  M5.Lcd.drawString("你好  世界", 160, 90, 1);    //在(160,60)处以字体1显示hello world
  M5.Lcd.drawString("Здравствуй  мир", 160, 120, 1);
  M5.Lcd.drawString("こんにちは  せかい", 160, 150, 1);
  delay(3000);

  M5.Lcd.fillScreen(0); //Fill the screen with black (used to clear the screen) is equivalent to clear ().  使屏幕充满黑色(用来清屏)等同于clear()
  M5.Lcd.setCursor(0, 30);  // Set the text cursor 0,30 position.  设置文本光标在(0,30)处
  M5.Lcd.printf("?????★☆??☉??????????????????????????????????????????????♀?♂?????????????????????????????????????????????????????????????????????????????????????????????A????????????????B????????????????C????????????????D????????????????E???");
  delay(3000);

  M5.Lcd.fillScreen(0);
  M5.Lcd.setCursor(0, 30);
  M5.Lcd.printf("?????????????F????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????A????????????????B????????????????");
  delay(3000);
