strip_tags with UTF-8 text

I have this code:

$string = strip_tags($string);

I cannot use it on UTF-8 text.

Error returned by validator: 'utf8' codec can't decode bytes in position 1026-1027: invalid data (maybe a high-bit character?)

Any idea how to fix this?

 

Try the explode function it does the same

 

Try to use other functions instead of strip_tags. There is many examples http://php.net/manual/fa/function.strip-tags.php
