php to excel - german Umlaute

Question

How can I alter this class to support German Umlaute (äöüÄÖÜ)? I tried to use utf8_encode($array) without succes. Also tried to change Content-Transfer-Encoding: binary to utf8<

Answer 1

foreach($v as $k1 => $v1 )
{
    $file .= $this->xlsWriteLabel( $tr1, $nn1, mb_convert_encoding($v1, 'UTF-16LE', 'UTF-8') );
    $nn1++;
}

You can also convert it this way.
