The problem is a little bit more complex. interp->codecs_initialized is set to
1 by _PyCodecRegistry_Init(), but the filesystem codec is not loaded yet. We
need another variable: interp->fscodec_initialized.
fscodec_subinterpreter.patch fixes this issue.
Note: the patch replaces also PyErr_Print() by PyErr_PrintEx(0) to avoid a
crash on error, if PyErr_PrintEx(0) is called before the sys module is
initialized. For example, if
PyModule_GetDict(_PyImport_FindBuiltin("builtins")) is NULL. Anyway, it's
useless to set sys attributes on error, because sys is destroyed just after
printing the error.
