From: vovchuck dot bogdan at gmail dot com
Operating system: Fedora 24
PHP version: 7.1.11
Package: mbstring related
Bug Type: Bug
Bug description:Bug in mbstring functions
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:
