nextion | A simple Nextion HMI library for Arduino

I'm working with some interesting devices and some of them uses micropython and on this part have problem with encodings.

I need to make two devices communicating by UART-protocol.

First device (may it be Nextion Display) sends to second device (STM-32 with micropython on board) string 'hellobruh' via UART,

second device gets bytesarray b'\x80\x9ef\x06\x9e\xe0\x9e\xfe\x9e\x18\x86\xf8f~\x80\x9e'

so the first thing I should try in my python script is to use .decode('utf-8') but no encodings works to decode it back to 'hellobruh'. I've tried windows-1251, cp-***, iso-****-*, ascii. Tried also with just usual python3 - no results, so I've put all these tags here - problem is not special for any devices. What am i doing wrong? This example is so simple as helloworld app on any platform/lang, so I think it is not incorrent settings setted by me or any hardware problem, I think it is just I don't understand in full way which encoding I get on second device or how to decode it. Thanks to all!

I'm a total noob and just starting out with PlatformIO and Arduino/ESP32. I also want to say thanks in advance to any help I can get.

Plan:

I have 2 ESP32's talking over ESP_NOW, I just can't verify the data being sent in order to progress with my project. Basically, I have a Nextion display that sends specific info to an ESP32 (tested and working) and that ESP32 is then to send that information via ESP_NOW to the other ESP32 which will translate it into serial data to send to an Arduino Due and perform some tasks.

Problem:

The issue I have is that when I test, I see the data I think I am transmitting, but when I try to Serial.print said info, I get "0 0 0 0". I'm not sure that I am sending OR receiving the data properly. All I know is that when I press the button on the Nextion, I get a response on the ESP32 that is not connected.
