PHPExcel Csv reader set encoding - php

Question

I have this so far, but when I read from my csv I get an empty value because it is a non utf-8 encoded csv file.
public function process_woe()
{
$objPHPExcel = new PHPExcel();
$woe_processed = $objPHPExcel->setActiveSheetIndex( 0 );
$objReader = PHPExcel_IOFactory::load( $this->woe_filepath );
$woe = $objReader->getActiveSheet();
$rcount = 1;
$rncount = 1;
}
This string returns an empty string when I try to write it on a utf-8 encoding:
"Caruso�s Prostate EZE MAX health indications:
� Management of symptoms Medically Diagnosed Prostate Enlargement
� Prostate gland health
� Antioxidant for the prostate gland"
When I try to use setInputEncoding() I get an error, for example:
$objReader->setInputEncoding('ISO');
$woe->setInputEncoding('ISO-8859-7');
$woe->setInputEncoding('ISO-8859-1');
Fatal error: Uncaught Error: Call to undefined method PHPExcel_Worksheet::setInputEncoding() –
