New submission from STINNER Victor <[email protected]>:
Currently, the code to select the encoding and error handler of sys.stdin,
sys.stdout and sys.stderr is run later in Py_Initialize(). I propose to move
most of this code into _PyCoreConfig_Read() and add stdio_encoding and
stdio_errors to _PyCoreConfig to easily let Python embedders to select the
encoding.
Attached PR implements this idea. During Py_Initialize(), the code still reads
the LC_CTYPE locale to choose the error handler if stdio_errors is NULL. This
check cannot be done earlier, since the LC_CTYPE locale is only set to the user
locale in Py_Initialize(): after _PyCoreConfig_Read().
The Py_SetStandardStreamEncoding() function has been added by Nick Coghlan in
bpo-16129.
This new pre-initialization API allows embedding
applications like Blender to force a particular
encoding and error handler for the standard IO streams.
