UnicodeDecodeError on RaspberryPi – Python

Hey everyone,

I ran into the following error while trying to read serial input on a Raspberry Pi hooked up to an Arduino via USB:

UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0za8 in position 0: invalid start byte

The solution was as follows:

#buffer_string = ser.read().decode('utf-8')
buffer_string = ser.read().decode('utf-8', errors='replace')
