UnicodeEncodeError: 'ascii' codec can't encode character '\u2026' in position 17: ordinal not in range(128)

Title: Resolve "Ordinal Not in Range" Error in Django Test Output

Problem: When running tests with Django, a UnicodeEncodeError occurs, indicating that an ASCII codec cannot encode the character at position 17. The presence of a Unicode character (\u2026, which is an ellipsis) in the text output of stdout is triggering the error, as the ASCII codec doesn't support characters beyond the 128 ordinal range.

Analysis: The error stems from the attempt to write a Unicode character (ellipsis …) to an output stream that is encoded in ASCII. This typically happens when developing on systems with limited locale support or when the Unicode-to-ASCII conversion is not handled properly by the program. The error suggests that Django's output mechanism is encountering a character that it is unable to process due to ASCII encoding limitations.

The root cause is the use of Unicode characters where ASCII handling is expected. This usually occurs in two situations:

1. The system default encoding does not support Unicode, and therefore falls back to ASCII.
2. The handling of strings in Django's commands or during test execution does not properly use a Unicode-compatible output stream.

Proposed Changes:

1. Correct Encoding Configuration:

   • Ensure the environment in which Django tests are run supports UTF-8 encoding. This might mean setting environment variables or ensuring the console can display and process UTF-8 characters.

2. Modify Django's Output Mechanism:

   • File: /testbed/django/core/management/base.py:
     • Modify the write method of the base management command class to ensure it uses a Unicode-aware stream (like UTF-8) or introduces error handling to safely replace or ignore non-ASCII characters.

3. Review Environment and Locale Settings:

   • Double-check the environment settings used during the testing process. Ensure that the locale and language settings favor UTF-8 to provide proper Unicode support. This includes settings in CI/CD environments when tests are automated.

4. Test and Validate:

   • After implementing the changes, rerun the tests to confirm that the UnicodeEncodeError is resolved. Make sure that no other parts of the code are adversely affected by these changes.
