Yes, that's the way things worked in Py2 (with def.encodding ascii). In Py3, that stuff is still there, but these API's are commented deprecated in Include/unicodeobject.h. These comments also recommend to use PyUnicode_AsUTF8String(). http://svn.python.org/view/python/branches/py3k/Include/unicodeobject.h?view=markup -- Lisandro Dalcín --------------- Centro Internacional de Métodos Computacionales en Ingeniería (CIMEC) Instituto de Desarrollo Tecnológico para la Industria Química (INTEC) Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) PTLC - Güemes 3450, (3000) Santa Fe, Argentina Tel/Fax: +54-(0)342-451.1594 _______________________________________________ Cython-dev mailing list [email protected] http://codespeak.net/mailman/listinfo/cython-dev
