unicode - How to display Japanese characters on a php page?

Question

I'm trying to display Japanese characters on a PHP page. No loading from the database, just stored in a language file and echo'ed out.

I'm running into a weird scenario. I have the page properly setup with UTF-8 and I test a sample page on my local WAMP server and it works.

The moment I tested it out our development and production servers the characters don't display properly.

This leads me to believe then that it's a setting in php.ini. But I haven't found much information about this so I'm not really sure if this is the issue.

Is there something fundamental I'm missing?

Thanks

You have to deliver the documents with the proper encoding declaration in the HTTP header field Content-Type.

In PHP you do this via the header function before the first data has been send to the client, so preferably as one of the first statements:

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

    // the rest
