<?php var_dump(json_encode(array("foo" => utf8_encode('è', "bar" => "bar")), json_last_error() === JSON_ERROR_UTF8); var_dump(json_encode(array("foo" => utf8_encode('è', "bar" => "bar"), JSON_PARTIAL_OUTPUT_ON_ERROR));

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
