Strange characters when using pound sign

问题

I've already got this line in my header..

<meta http-equiv="content-type" content="text/html; charset=utf-8">

I have an input form and when I enter a pound sign £ it's coming out with a strange character before it. The values are stored in the database and then displayed but the problem seems to be before we even get to the database.

If I submit my form and then print_r the $_POST array I get:

[field2_title] => £ Question

I thought the issue might be with the code igniter $this->input->post() function but it's happening before then. Other than adding the meta tag which I've already done I'm not sure what else to try?

I have also tried this..

<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1">

In your view, try adding the following code:

<?php header('Content-Type: text/html; Charset=UTF-8'); ?>
