I think it comes down to what locales are available on the system? Based on what I saw in CPython\u0027s source [0] I started playing around with some simple C code and seeing what encodings I could get:\n\n#include \u003clanginfo.h\u003e\n#include \u003clocale.h\u003e\n#include \u003cstdio.h\u003e\nint main(int argc, char **argv){\n    setlocale(LC_ALL, \"\");\n    printf(\"%s\\n\", nl_langinfo(CODESET));\n    return 0;\n}\n\nCompile and run it with a fresh env and I get\n\n $ env -i ./a.out \n ANSI_X3.4-1968\n\nSet LC_ALL:\n\n $ env -i LC_ALL\u003deo ./a.out \n UTF-8\n\nBut those were both on my laptop which has eo as a locale:\n\n $ locale -a | grep eo\n eo\n eo.utf8\n ka_GE.georgianps\n\nOn another box that *doesn\u0027t*:\n\n $ locale -a | grep eo\n ka_GE.georgianps\n\n $ env -i ./a.out \n ANSI_X3.4-1968\n\n $ env -i LC_ALL\u003deo ./a.out \n ANSI_X3.4-1968\n\n $ env -i LC_ALL\u003dfr_FR.UTF-8 ./a.out \n UTF-8\n\nI *think* py37 resolved this in https://www.python.org/dev/peps/pep-0540/\n\n[0] See\n\n- https://github.com/python/cpython/blob/v3.6.8/Lib/locale.py#L631-L644 which calls\n- https://github.com/python/cpython/blob/v3.6.8/Lib/_bootlocale.py#L23-L34\n\nI also peeked at some sys module code like\n\n- https://github.com/python/cpython/blob/v3.6.8/Python/sysmodule.c#L296-L304 that uses vars initialized in\n- https://github.com/python/cpython/blob/v3.6.8/Python/pylifecycle.c#L981-L1021 which calls\n- https://github.com/python/cpython/blob/v3.6.8/Python/pylifecycle.c#L225-L245","commit_id":"ff950cc00adda06cf1721df9afc8a0ca7e4d94b4"}]}
