Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Description:
------------
I use Zend Framework 1 with PHP 7.1.11. And any calls of multibyte functuions will produce this
error
private function convert_recheck($var)
{
if (is_array($var)) {
$new = array();
foreach ($var as $key => $val) {
$new[$key] = $this->convert_recheck($val);
}
$var = $new;
} else if (is_string($var)) {
if (!mb_detect_encoding($var, 'UTF-8', true)) {
$var = iconv("CP1251", "UTF-8", $var);
}
}
return $var;
}
Actual result:
