How about testing on Windows? > If computing the final length is cheap (eg. if it's always the same), > it's always faster to use UnicodeWriter with a preallocated buffer. That's not a particularly surprising discovery, is it? ;-) Regards Antoine. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
