调研方向

Start by reviewing linked PR gh-121219, then compare the historical convert_surrogates.py file and codecs_convert_escapes patches. Read dependencies bpo-22286 and bpo-23676 to understand the required error-handler support; done means the agreed surrogate-cleaning utilities and related behavior are implemented and validated.
