I'm trying to wrap my head around this but I don't seem to grasp the concept.

Input from a form (utf-8) on a html 5(utf-8) page gets posted to a ci project (utf-8) then when I insert an & symbol it get's posted correctly and I encode the html entities so I can show them on my website. Then if I do exactly the same thing with an currency symbol e.g. € the input get's deleted!. I found the input get's deleted in the utf-8 class(uni) in the function clean_string. Now I'm thinking my input is crooked. How can I make sure I post using utf-8?

form and html header code

Code:
<!DOCTYPE HTML> 

&lt;html&gt; 

  &lt;head&gt; 

    &lt;title&gt;Title goes here!&lt;/title&gt; 

    &lt;meta charset="UTF-8" /&gt;

Code:
&lt;form action="http://localhost/edit/1" method="post" accept-charset="utf-8" id="edit_form"&gt;

I found that the problem is in this function in the utf8.php file.

Code:
function clean_string($str)

    {

        if ($this->_is_ascii($str) === FALSE)

        {

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

        }

        return $str;

    }

What I don't understand is that when I input an UTF-8 string with a currency sign(EURO) in it is doesn't return anything. This is also not as how it should work. Because of the //IGNORE tag it should ignore the errors and return the known characters.

What am I overlooking or is the iconv just broken?

Try it without using html entities and see if it works.

The problem is even before htmlentities when the post input gets cleaned. the title is a bit misleading, it has nothing to do with htmlentities...

Well I think this is the problem, this is from php.net iconv

Code:
&lt;?php

$text = "This is the Euro symbol '€'.";

echo 'Original : ', $text, PHP_EOL;

echo 'TRANSLIT : ', iconv("UTF-8", "ISO-8859-1//TRANSLIT", $text), PHP_EOL;

echo 'IGNORE   : ', iconv("UTF-8", "ISO-8859-1//IGNORE", $text), PHP_EOL;

echo 'Plain    : ', iconv("UTF-8", "ISO-8859-1", $text), PHP_EOL;

?&gt; 

// Displays

Original : This is the Euro symbol '€'.

TRANSLIT : This is the Euro symbol 'EUR'.

IGNORE   : This is the Euro symbol ''.

Plain    :

Notice: iconv(): Detected an illegal character in input string in .\iconv-example.php on line 7

This is the Euro symbol '

I think this needs to be reported to the Reactor Team!
