Fatal error: Cannot use [] for reading

I'm getting this error

Fatal error: Cannot use [] for reading in... on line 26

Checking all the threads that have been made here on this error, I still cannot figure it out. Looking at my code there's nothing I'm doing wrong. 

<?php
class Person
{
    //Variables for personal information//
    private $navn;
    private $adresse;
    private $postnummer;
    private $poststed;
    private $telefonnummer;
    private $fodselsdato;
    public function __construct($navn, $adresse, $postnummer, $poststed, $telefonnummer, $fodselsdato)
    {
        $this->navn = $navn;
        $this->adresse = $adresse;
        $this->postnummer = $postnummer;
        $this->poststed = $poststed;
        $this->telefonnummer = $telefonnummer;
        $this->fodselsdato = $fodselsdato;
    }
    //Creates an array to store education for a person//
    private $utdanning = array();

    //Function to add education to the array//
    public function leggTilUtdanning(Utdanning $utdanning)
    {
        $this->utdanning[] = $utdanning;
    }
}
//Class for education
class Utdanning
{
    private $institusjon;
    private $studieretning;
    private $grad;
    private $startet;
    private $ferdig;

    public function __construct($institusjon, $studieretning, $grad, $startet, $ferdig)
    {
        $this->institusjon = $institusjon;
        $this->studieretning = $studieretning;
        $this->grad = $grad;
        $this->startet = $startet;
        $this->ferdig = $ferdig;
    }
}
$person1 = new Person('Dave Lewis', 'Downing Street 14', 0442, 'Northville', 98765432, '17.05.1975');
$utdanning = new Utdanning('Harvard', 'Economics', 'Bachelor', 2013, 2016);
$person1->leggTilUtdanning($utdanning);
?>

The error comes from the line inside the function where I'm trying to add an Utdanning-object to the array. It's funny, cause I tried this very same method of doing it on another project, using the exact same syntax, and it worked perfectly. Furthermore, I don't understand why it says I'm trying to read from the array, when I'm actually adding to it.

Does anyone have an idea what's going on here?

EDIT: I circled the problem and made a more simple version of the code so you can see for yourself.

So, just to mark this solved, I got rid of the problem simply by rewriting the characters inside the method leggtilUtdanning. Appears to have been some sort of character encoding-problem like you pointed out, but I have absolutely no idea how that happened. Anyway, thanks for all the help.
