not sure if this message belongs on [email protected] or [email protected] or elsewhere, i'll just try here first and see what happens,
recently made some tests to check performance of UTF8 validators, and in that (simple non-comprehensive) test, preg_match() is ~33 times faster than mb_check_encoding(), and mb_check_encoding() is less than half the speed of iconv() (even though iconv isn't designed for validating at all, and makes a full copy of the string), can someone shed some light on this? why does mb_check_encoding seem to be so much slower than the alternatives? benchmark code+results is here https://stackoverflow.com/a/68690757/1067003
