Research direction

The issue names no files, tests, or entry points. Start by locating CPython's UTF-8 decoding path and its handling of surrogate code points, then determine the expected diagnostic and add a focused regression test. Done means the decoding failure reports a clear, actionable error without changing unrelated decoding behavior.
