UnicodeDecodeError: ‘utf-8’ can’t decode byte 0x90 in position 4024984: invalid start byte

Question

I’m running a subprocess in full trace mode and displaying it using logger.info()

> std = subprocess.run(subprocess_cmd, shell=True,
> universal_newlines=True, stdout=subprocess.PIPE,
> stderr=subprocess.PIPE)
> 
> all_stdout = all_stdout + std.stdout + ‘\n’ all_stderr = all_stderr +
> std.stderr + ‘\n’
> 
> logger.info(‘\nstdout:\n’ + all_stdout + ‘\nstderr:\n’ + all_stderr)

But I’m getting the below error when the subprocess is getting printed.

UnicodeDecodeError: ‘utf-8’ codec can’t decide byte 0x90 in position 4024984:invalid start byte

I have tried giving universal_lines as False but it throws TypeError: must be str, not bytes.

I have also tried this - std = subprocess.run(subprocess_cmd, shell=True, stdout=subprocess.PIPE,

> stderr=subprocess.PIPE, env=environ, encoding=‘utf-8’)

This gives me same UnicodeDecodeError.
