This is my function that always works, regardless of encoding:

function RemoveBS($Str) {  
  $StrArr = str_split($Str); $NewStr = '';
  foreach ($StrArr as $Char) {    
    $CharNo = ord($Char);
    if ($CharNo == 163) { $NewStr .= $Char; continue; } // keep £ 
    if ($CharNo > 31 && $CharNo < 127) {
      $NewStr .= $Char;    
    }
  }  
  return $NewStr;
}

How it works:

echo RemoveBS('Hello õhowå åare youÆ?'); // Hello how are you?
