在 Python 中使用混合 UTF-8 编码解码响应

Question

I'm downloading data from a website using aiohttp and I'm getting a bytes object as a response but I'm having an hard time decoding it. This is an example of the reponse I get

b'\\r\\nLocalit\xc3\xa0' # Località
b'\\u003cdiv\\u003e12/09/2019\\u003c/div\\u003e\\r\\n' # <div>12/09/2019</div>

From what I understand it has normal unicode for text and escaped unicode for the html tags and line feed. If I try to decode it using "str(content, "utf-8")" I still have the html tags in this format

\u003cdiv \u003e12/09/2019\u003c/div\u003e\r\n

Should I just do a manual .replace("\\u003\u0026quot;, "<") for every tag or is there a more elegant solution?

You could use the 'unicode-escape' codec to convert the unicode part, then reencode transparently to bytes (latin-1 is convenient for this, as is provides a 1-to-1 correspondance between bytes and chars), then decode as 'utf-8':

b = b'\\u003cdiv\\u003e12/09/2019\\u003c/div\\u003e\\r\\n\\r\\nLocalit\xc3\xa0'
b.decode('unicode-escape').encode('latin1').decode('utf8')
# '<div>12/09/2019</div>\r\n\r\nLocalità'
