'utf-8' codec can't decode byte 0x8b in position 0: invalid start byte

    print(f) #f = b'\x8b\x86pJ'
    response = HttpResponse(content_type="text/plain")
    response['Content-Disposition'] = 'attachment; filename=file.txt'

    filename = f
    print(filename) # filename = b'\x8b\x86pJ'
    download = filename.decode('utf-8')
    response.write(download)
    print(response)

You can try

def create_file(f):
    print(f) #f = b'\x8b\x86pJ'
    response = HttpResponse(content_type="text/plain")
    response['Content-Disposition'] = 'attachment; filename=file.txt'

    filename = f
    print(filename) # filename = b'\x8b\x86pJ'
    download = filename.decode('latin-1')
    response.write(download)
    print(response)

    return response
