bpo-36301 created a very strict separated between Python initialization and a new "pre-initialization" which is responsible to configure encodings and memory allocators.

Nick Coghlan proposed to disable UTF-8 Mode and C locale coercion by default in the pre-initialization, so the LC_CTYPE locale is not coerced by Python when it's embedded in an application.

Maybe the UTF-8 Mode can be automatically enabled (depending on the LC_CTYPE locale), but not the C locale coercion?

This issue is related to bpo-36202: Calling Py_DecodeLocale() before _PyPreConfig_Write() can produce mojibake.
