I think I'm missing something simple with input arguments and them having characters with accent marks. I have a php file that can take arguments `example.com/myphpfile.php?ar1=somestring` and I cycle through the characters in `arg1` to do stuff and when I use characters with accent marks, it doesn't seem to work correctly. If I have `arg1=niño` my if statements don't seem to work and it is set up like this to go through:

```
$strArr = str_split($_GET['arg1']);
foreach ($strArr as &$char) {
    // do some stuff for each character       
}

```

If I use `echo $_GET['arg1'];` and use `arg1=niño`, I get `niÃ±o`. Am I doing something wrong with each character?
