3 Solutions in your case...
First, you can create your database in the UTF-8 charset, conversions is not needed.
Second, you can test this code...
htmlentities(urldecode( $my_var_to_utf8 ), ENT_QUOTES, 'UTF-8');
If it don't works, try this function...
function to_utf8( $string ) {
// From http://w3.org/International/questions/qa-forms-utf-8.html
if ( preg_match('%^(?:
[\x09\x0A\x0D\x20-\x7E] # ASCII
| [\xC2-\xDF][\x80-\xBF] # non-overlong 2-byte
| \xE0[\xA0-\xBF][\x80-\xBF] # excluding overlongs
| [\xE1-\xEC\xEE\xEF][\x80-\xBF]{2} # straight 3-byte
| \xED[\x80-\x9F][\x80-\xBF] # excluding surrogates
| \xF0[\x90-\xBF][\x80-\xBF]{2} # planes 1-3
| [\xF1-\xF3][\x80-\xBF]{3} # planes 4-15
| \xF4[\x80-\x8F][\x80-\xBF]{2} # plane 16
)*$%xs', $string) ) {
return $string;
} else {
return iconv('CP1252', 'UTF-8', $string);
}
}
To use...
echo(to_utf8($my_var_to_utf8));
