Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

  [FAILED tests/unit/activation/test_csh.py::test_csh[no_prompt] - UnicodeDecodeError: 'utf-8' codec can't decode byte 0x92 in position 99: invalid start byte
FAILED tests/unit/activation/test_csh.py::test_csh[with_prompt] - UnicodeDecodeError: 'utf-8' codec can't decode byte 0x92 in position 99: invalid start byte
========== 2 failed, 244 passed, 26 skipped, 59 deselected in 17.50s ===========
]: [Cause: Python's utf-8 decoder encountered a byte (0x92) at position 99 in a file that it couldn't interpret as a valid UTF-8 character.]

Issue: This error message indicates a problem with character encoding during your RPM build process caused by 2 failed unit tests.
Resolution: Incorrect File Encoding: The file causing the error might be encoded in a format other than UTF-8. Here are some ways to address this:

Identify the encoding: Try tools like file or chardet to detect the actual encoding.
Specify encoding when opening the file: In your test script, open the file with the correct encoding using with open("file.txt", encoding="encoding_name") as f:.
Fix the source: If you have control over the file's origin, try re-saving it with UTF-8 encoding.
Corrupted File: The file itself might be corrupted. Try obtaining a fresh copy or re-generating the file.
