…embers PyConfig.stdin_encoding, PyConfig.stdout_encoding and PyConfig.stderr_encoding allow the standard streams to have different encodings. In the legacy Windows stdio mode they are initialized with the encoding of the device the corresponding stream is connected to, instead of the ANSI code page.

PyConfig.stdin_encoding,PyConfig.stdout_encodingandPyConfig.stderr_encodingallow the standard streams to have different encodings. In the legacy Windows stdio mode they are initialized with the encoding of the device the corresponding stream is connected to, as suggested by @eryksun.This removes a documented member of the public
PyConfig, so it needs a decision about embedders. #155416 achieves the same result without changing the API, and #155415 is the minimal fix which is suitable for backporting.
