Sending Polish characters with PHP

Question

I have an issue and I can find a lot of questions about this issue on this board. I would like Polish characters by POST :

When I send with a form by POST the following data:

Ciało wielbłądów osiąga długość do 3 m. Ich szyja jest długa, łukowato wygięta; głowa długa,

PHP displays the following:

<p>Ciało wielbłądów osiąga długość do 3 m. Ich szyja jest długa, łukowato wygięta; głowa długa,

Even when directly doing:

exit(print_r($_POST));

At the top of the page.

What have I done so far?

I tried to use HTML entities

exit(htmlentities($_POST['EditorField'], ENT_NOQUOTES, 'UTF-8'));

I tried to use utf8_decode

exit(utf8_decode($_POST['EditorField']));

I have set the internal encoding at UTF-8 :

mb_internal_encoding('UTF-8');

This takes place very early in the frameworks initialization class. I hope there is something that I have missed and could be working anyway.

Edit:

I added the following :

<form action="" method="post" accept-charset="utf-8">

accept-charset="utf-8"

And I removed the TinyMCE editor

Still no luck!

CiaÅ‚o wielbÅ‚Ä…dów osiÄ…ga dÅ‚ugość do 3 m. Ich szyja jest dÅ‚uga, Å‚ukowato wygiÄ™ta; gÅ‚owa dÅ‚uga

Edit: In the mean time I did find the following:

Adding:

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

This does the trick for the $_POST to be correctly send. I thought that this was the same as :

mb_internal_encoding('UTF-8');

But I was wrong.

There is a small problem that still occurs though. When saving the data with PDO it still truncates the data.

I my opinion I still use the correct settings to initialize the connection

    self::$DbConnection[$ConnectionName]->exec('SET CHARACTER SET utf8');
}

(* still I make a mistake somewhere of course. But now I have to find it... *)

Solved!! I hope someone could still up me this post because I found the solution. And it lays in a total different direction than all other noted problems on this board:

Required :

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

BUT REMOVED!! :

                        PDO::MYSQL_ATTR_INIT_COMMAND        =>      'SET NAMES utf8'

I also removed :

self::$DbConnection[$ConnectionName]->exec('SET CHARACTER SET utf8');

Tried both of the mentioned above individually. But now it works.
