Remove non-utf8 characters from string

Question

Im having a problem with removing non-utf8 characters from string, which are not displaying properly. Characters are like this 0x97 0x61 0x6C 0x6F (hex representation)

Answer 1

The text may contain non-utf8 character. Try to do first:

$nonutf8 = mb_convert_encoding($nonutf8 , 'UTF-8', 'UTF-8');
