日志文件不是 UTF-8

Question

I am unable to get a log file in Python due to an error when attempting to open the file: The document was not UTF-8 valid.

I have tried the following:

import logging
logging.basicConfig(filename='/home/pi/Desktop/logEL.log', filemode='w', format=u'%(asctime)s - %(message)s', level=logging.DEBUG, encoding='utf-8')

as well as:

import logging

root_logger= logging.getLogger()
root_logger.setLevel(logging.DEBUG) # or whatever
handler = logging.FileHandler('/home/pi/Desktop/logEL.log', 'a', 'utf-8')
formatter = logging.Formatter(u'%(asctime)s - %(message)s')
handler.setFormatter(formatter) 
root_logger.addHandler(handler)

Opening the log file:

Answer 1

Opening the log file with nano instead of the GUI seems to be the trick.
