    if (mysqli_connect_errno())
    {
        echo "Nie Udało się połączyć z bazą danych: " . mysqli_connect_error();
    }

    $result = mysqli_query($con,"SELECT * FROM Delegacje");

    echo "<table>
<tr>
<th>Imię i Nazwisko</th>
<th>Data od</th>
<th>Data do</th>
<th>Miejsce wyjazdu</th>
<th>Miejsce przyjazdu</th>
</tr>";

    while($row = mysqli_fetch_array($result))
    {
        echo "<tr>";
        echo "<td>" . $row['Imie i Nazwisko'] . "</td>";
        echo "<td>" . $row['Data od'] . "</td>";
        echo "<td>" . $row['Data do'] . "</td>";
        echo "<td>" . $row['Miejsce wyjazdu'] . "</td>";

Try opening file in regular notepad go save as and under encoding chose UTF-8, that could help too.
