CKEditor插入特殊字符

I have several wysiwyg textareas using CKEditor 4. I store the data in a MYSQL database. If I leave the textarea blank and submit it to the database, CKEditor automatically inserts a special character  Â. Anyone know a fix for this?

HTML:

<textarea cols="60" rows="8" name="description" class="ckeditor"></textarea>

PHP:

// Handler stuff here

$name = $_POST['name'];
$title = $_POST['title'];
$description = $_POST['description'];

$sql = "INSERT INTO `aircraft`
                (name,
                description,
                title) 
                VALUES (?, ?, ?)";
$sth = $this->dbh->prepare($sql);
$sth->execute(array($name, $description, $title));

You have actually faced a bug that was fixed just a while ago: http://dev.ckeditor.com/ticket/9732

Redownload CKEditor, clear browser's cache and the issue should be gone.

3 years later and this is still a problem ...

user1867004's suggestion worked for me.

Add this to config.js:

config.enterMode = CKEDITOR.ENTER_BR;
config.shiftEnterMode = CKEDITOR.ENTER_P;

Only change :

OLD

<script type="text/javscrip" src="ckeditor/ckeditor.js"></script>

NEW

<script type="text/javscrip" src="ckeditor/ckeditor.js" charset="utf-8"></script>

Have a good day
