I use iconv php function but some characters doesn't convert correctly:
...
$s = iconv('UTF-16', 'UTF-8', $s);
...
$s = iconv('UTF-16//IGNORE', 'UTF-8', $s);
...
$s = iconv('UTF-16LE', 'UTF-8', $s);
...
$s = iconv('UTF-16LE//IGNORE', 'UTF-8', $s);
...
I also try mb_convert_encoding function but can't solve my problem.
