Josh Rosenberg added the comment: How often do people need to convert to do platform independent locale encoding before Python is initialized? Encouraging use of platform dependent wchar_t's seems like a bad idea when PyUnicode abstracts away the difference ever since 3.3 released. -- nosy: +josh.rosenberg ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18395 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Thomas Kluyver added the comment: You seem to need wchar_t to call Py_Main and Py_SetProgramName. I think there's an example in the docs which is wrong, because it appears to pass a char* to Py_SetProgramName: https://docs.python.org/3.4/extending/embedding.html#very-high-level-embedding -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18395 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue18395] Make _Py_char2wchar() and _Py_wchar2char() public
New submission from STINNER Victor: The Python C API has two very useful functions: _Py_char2wchar() and _Py_wchar2char(). They must be used to handle correctly undecodable byte sequences. _Py_char2wchar() and _Py_wchar2char() use the surrogateescape error handler (PEP 383). _Py_char2wchar() forces also the ASCII encoding on FreeBSD and Solaris when the LC_CTYPE locale is C. Py_Main() expects an array of wide character strings (wchar_t*) for the command line argument, whereas main() gets an array or byte strings (char*). _Py_char2wchar() must be used to be able to call Py_Main(). I propose the following names: wchar_t* Py_DecodeLocale(const char* arg, size_t *size); char* Py_EncodeLocale(const wchar_t *text, size_t *error_pos); See Python/fileutils.c for more information about these functions. Python 3.3 has already higher level functions (calling _Py_char2_wchar() and _Py_wchar2char()): PyObject* PyUnicode_DecodeLocale(const char *str, const char *errors); PyObject* PyUnicode_EncodeLocale(PyObject *unicode, const char *errors); But these functions cannot be used before Python is initialized. -- messages: 192557 nosy: haypo priority: normal severity: normal status: open title: Make _Py_char2wchar() and _Py_wchar2char() public versions: Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18395 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
