Describe the bug
The issue pertains to the charset_normalizer.detect() method, which fails to perform valid encoding detection for expression sequences. Specifically, the method incorrectly recognizes the sequence as Big5 and returns it as a Chinese character. This behavior can be observed with the provided code snippet:

To Reproduce
Execute the code snippet, where the charset_normalizer.detect() method misidentifies the encoding of the sequence.

import charset_normalizer
text = b"What Actions Will Keep Us at 1.5-2\xbaC?"
text.decode(charset_normalizer.detect(text)["encoding"])

Expected behavior
The expected behavior can be demonstrated using the chardet library, which accurately recognizes the encoding as ISO 8859-1. The correct degree character is then returned from the sequence:

import chardet
text = b"What Actions Will Keep Us at 1.5-2\xbaC?"
text.decode(chardet.detect(text)["encoding"])

Logs

charset-normalizer:
What Actions Will Keep Us at 1.5-2慢?

chardet:
What Actions Will Keep Us at 1.5-2ºC?

{'encoding': 'ISO-8859-1', 'confidence': 0.73, 'language': ''}  # chardet
{'encoding': 'Big5', 'language': 'Chinese', 'confidence': 1.0}  # charset-normalizer
