Answer 1

Use the iconv function:

 iconv('utf-8','iso-8859-1//TRANSLIT',$text);

Answer 2

You can represent the Unicode characters with character references by using mb_convert_encoding:

mb_substitute_character('entity');
echo mb_convert_encoding($str, 'ISO-8859-1', 'UTF-8');

With mb_substitute_character you specify how invalid characters (characters of the input character set that are not present in the output character set) should be handled. In this case entity specifies to replace invalid characters by a corresponding HTML character reference.
