It's actually 3 lines:
function str_is_utf8($str) {
return $str == "" || htmlspecialchars($str, 0, "UTF-8");
}
WTF should this do?
this won't return boolean
The reason it works is that
1) || coerces the operands into booleans (if they get to be evaluated)
2) htmlspecialchars returns "" on bad input sequence
3) (bool) "" === false
But even if you didn't know these things, you should have bothered to at
least test it before sending this response.
