Question

I am trying to output a sigma character (σ) in a label in a FusionChart graph. How can I specify that character in a PHP string? I have tried the htmlentity σ, but it is not interpreted correctly by the graph. Is there any way to specify the character in PHP using some sort of character code?

Answer 1

You need to make sure you’re sending the correct headers when outputting.

<?php

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

$char = utf8_encode(html_entity_decode('&sigma;'));

echo $char;

This will output the character.

Edit:

If passing the character into the graph doesn’t work, then the software doesn’t support UTF-8.
