What are some potential solutions for displaying the Euro symbol in a PHPLOT-generated graphic?

When displaying the Euro symbol in a PHPLOT-generated graphic, one potential solution is to use the UTF-8 encoding for the Euro symbol (€). This can be achieved by setting the appropriate header in the PHP script and using the UTF-8 encoded Euro symbol in the text to be displayed on the graphic. 

<?php
header('Content-Type: text/html; charset=utf-8');

require_once 'phplot.php';

$data = array(
    array('', 30),
    array('€', 70),
);

$plot = new PHPlot(800, 600);
$plot->SetDataType('text-data');
$plot->SetDataValues($data);
$plot->SetPlotType('bars');
$plot->DrawGraph();
