> https://bugs.python.org/issue25631 "Segmentation fault with invalid Unicode command-line arguments in embedded Python" (actually 'fixed' since it now abort()s)

This issue is different: it is about the Py_Main() function called explicitly when Python is embedded in an application. Python fails if the command line contains a *wide character* outside the [U+0000; U+10ffff] range.

This issue is about Python on Linux in which case Py_BytesMain() is used to decode *bytes* from the command line.
