ascii codec cant decode byte 0xe9

Question

I have done some research and seen solutions but none have worked for me.

Python - 'ascii' codec can't decode byte

This didn't work for me. And I know the 0xe9 is the é character. But I still can't figure out how to get this working, here is my code

output_lines = ['<menu>', '<day name="monday">', '<meal name="BREAKFAST">', '<counter name="Entreé">', '<dish>', '<name icon1="Vegan" icon2="Mindful Item">', 'Cream of Wheat (Farina)','</name>', '</dish>', '</counter >', '</meal >', '</day >', '</menu >']
output_string = '\n'.join([line.encode("utf-8") for line in output_lines])

And this give me the error ascii codec cant decode byte 0xe9

And I have tried decoding, I have tried to replace the "é" but can't seem to get that to work either.

You are trying to encode bytestrings:

>>> '<counter name="Entreé">'.encode('utf8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 20: ordinal not in range(128)

Python is trying to be helpful, you can only encode a Unicode string to bytes, so to encode Python first implictly decodes, using the default encoding.

The solution is to not encode data that is already encoded, or first decode using a suitable codec before trying to encode again, if the data was encoded to a different codec than what you needed.

If you have a mix of unicode and bytestring values, decode just the bytestrings or encode just the unicode values; try to avoid mixing the types. The following decodes byte strings to unicode first:

def ensure_unicode(v):
    if isinstance(v, str):
        v = v.decode('utf8')
    return unicode(v)  # convert anything not a string to unicode too

output_string = u'\n'.join([ensure_unicode(line) for line in output_lines])
