XML Parsing with lxml in Python - Handling Unexpected UnicodeDecodeError

Can someone help me understand I'm testing a new approach and I'm prototyping a solution and I'm using the `lxml` library in Python 3.9 to parse an XML file, and I'm running into a `UnicodeDecodeError`. The XML file is encoded in UTF-8, but when I attempt to load it, I get the following behavior: `UnicodeDecodeError: 'utf-8' codec need to decode byte 0x9c in position 123: invalid start byte`. I've tried specifying the encoding explicitly while opening the file: ```python from lxml import etree with open('data.xml', 'r', encoding='utf-8') as file: xml_content = file.read() tree = etree.fromstring(xml_content) ``` This approach still raises the same behavior, and I've verified that the file doesn't contain any invalid bytes manually. I also tried using a different encoding like 'ISO-8859-1' but that resulted in a different behavior regarding unexpected byte sequences. What could be causing this scenario, and how can I properly handle the file? I want to maintain the correct encoding and avoid these errors while ensuring efficient XML parsing. For reference, this is a production application. Any feedback is welcome! This issue appeared after updating to Python LTS.
