How to display UTF8 characters in M5Stack Fire

[gbastos]

Hello everyone,

I'm dealing with M5Stack Fire, and I'm trying to display Portuguese characters on display, until now without success.

So basically a simple program like

#include <M5Stack.h>

void setup() {
  // Initialize the M5Stack
  M5.begin();
  
  // Clear the screen and display a message
  M5.Lcd.clear();
  M5.Lcd.setCursor(50, 50);
  M5.Lcd.print("Configuração está ok"); //Meaning: configuration it's ok
}

void loop() {
  // No need to put anything in loop for this example
}

But this does not print the ç character, ã or even á.
I tried to load a custom font, but this is not good, because then I can't set it's size dynamically.

Is there any way to make the M5Stack fire support these characters?
