Calling stream() or astream() on ChatPerplexity with a stop argument raises TypeError because the streaming implementation incorrectly sends stop_sequences (an Anthropic parameter) to Perplexity's Chat Completions API, which only accepts stop. The bug breaks streaming for any user passing stop sequences.
Two unit tests in the langchain package (tests/unit_tests/test_version.py and tests/unit_tests/test_dependencies.py) open pyproject.toml using Path.open() without specifying encoding. On Windows systems with a non-UTF-8 locale (e.g., cp936), Python defaults to the locale encoding, causing UnicodeDecodeError when encountering UTF-8 bytes. The fix is to pass encoding="utf-8" to the open calls.
