I am developing an app using Codeigniter. In this app I got a form with user data.
All works fine if the user submits a form with only A-Z characters but if he is using
special characters like ä,é,î,ø,ù the value of that field is not submitted to the controller!

This problem drives me crazy. I cannot figure out why the field is ignored? The same
field works fine with A-Z characters as said.

Update

In config I got: $config[‘charset’] = ‘UTF-8’;
I am making a POST request.

This is my View code:

    <?php echo form_open('accounts/save', 'name="theform"'); ?>

<p><?php echo form_input('firstname', null); ?></p>

<p><?php echo form_input('lastname', null); ?>

<div id="button_green">

    <a href="javascript: submitform()">Save the data</a>

</div> <!-- End of button_green -->

<?php echo form_close(); ?>

Update 2

After a looong chat with the excellent @motto and @slavic it came down to a bug
with PHP 5.3.6 (which I am using).

More information about the bug here: https://github.com/EllisLab/CodeIgniter/issues/261

This is the line causing the problem:

$str = @iconv(‘UTF-8’, ‘UTF-8//IGNORE’, $str);
