PHPExcel编写奇怪的字符

Question

I have a PHP file with a query in sqlsrv, runs well, generated an Excel file with either PHPExcel or without the library, the Excel file is generated either but in the next cell down after writing the results writes strange symbols like this:

ÐÏࡱá;þÿ þÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿþÿÿÿ

Does anyone know how to fix it? I tested locally, on a remote server, with different versions of PHP and it goes the same....

Here´s the code:

<?php

require_once 'PHPExcel.php';
require_once 'PHPExcel/IOFactory.php';

$server = "192.168.1.240";
$info = array("Database"=>"Ariel","UID"=>"sa","PWD"=>"" );
$conn = sqlsrv_connect($server, $info);
$param = array('ReturnDatesAsStrings'=> true);
$opt = array("Scrollable" => SQLSRV_CURSOR_KEYSET);

$objPHPExcel = new PHPExcel();

$fec1 = $_GET["fecha1"];
$fec2 = $_GET["fecha2"];
$suc = $_GET["sucursal"];
$nom = 'Nombre';
$per = 'Personal';
$reg = 'Registro';
$hreg = 'Hora Registro';
$con = 'Concepto';
$fecd = 'Fecha';
$obs = 'Observaciones';
$dep = 'Departamento';

$sql = "select personal, (nombre +' '+apellidopaterno+' '+apellidomaterno) as '$nom', departamento as '$dep'
from personal where nombre like '%$nom%' and estatus = 'Alta' and sucursaltrabajo = '$suc'";

$sql2 = "select (p.nombre +' '+p.apellidopaterno+' '+p.apellidomaterno) as '$nom', ad.personal as '$per',ad.registro as '$reg', ad.horaregistro as '$hreg',ad.concepto as '$con',
ad.fechad as '$fecd', ad.observaciones as '$obs'
from asiste a join asisted ad on a.id= ad.id join personal p on p.personal = ad.personal 
where ad.sucursal = '$suc' and a.fechaemision between '$fec1' and '$fec2' order by ad.personal,ad.fechad";

$query = sqlsrv_query($conn, $sql2);

$query2 = sqlsrv_query($conn, $sql);

$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setCellValue('A3', 'Nombre');
$objPHPExcel->getActiveSheet()->setCellValue('B3', $nom);
$objPHPExcel->getActiveSheet()->setCellValue('A4', 'Departamento');
$objPHPExcel->getActiveSheet()->setCellValue('B4', $dep);
$objPHPExcel->getActiveSheet()->setCellValue('H4', 'Fecha');
$objPHPExcel->getActiveSheet()->setCellValue('I4', date("d/M/Y"));

echo "<table border='1'><tr>";
echo "<th>$nom</th>";
echo "<th>$per</th>";
echo "<th>$reg</th>";
echo "<th>$hreg</th>";
echo "<th>$con</th>";
echo "<th>$fecd</th>";
echo "<th>$obs</th>";

while ($row = sqlsrv_fetch_array($query)) {

    $nom = $row['Nombre'];
    $per = $row['Personal'];
    $reg = $row['Registro'];
    $hreg = $row['Hora Registro'];
    $con = $row['Concepto'];
    $fecd = $row['Fecha'];
    $obs = $row['Observaciones'];

    echo "<tr>";
    echo "<th>".$nom."</th>";
    echo "<td>".$per."</td>";
    echo "<td>".$reg."</td>";
    if (!empty($hreg)) {
        echo "<td>".$hreg."</td>";
    }
    echo "<td>".$con."</td>";
    if (!empty($fecd)) {
        echo "<td>".$fecd->format("Y-m-d H:i:s")."</td>";
    }
    echo "<td>".$obs."</td>";
}

echo "</table>";
