使用拉丁字符的HTML和MySQL问题

Question

I am trying to create my first web page using Yii, PHP and MySQL. I have some problems using latin characters. When I write these characters I can't show them correctly, for example:

ID: 1   
Username: José MiguelEDITADO
Password: contraseñaJosemi 

Besides, I have the same problem when I try to store this characters in the DB. I mean, when I complete a form field and click on submit, if one of theses fields have latin characters, the DB only store the text of the field up to the latin character. For example:

If write "María" in the form field the DB store "Mar" inthe corresponding register.

I know that I have a problem with the charset but I don't know why. In the db array of my main.php I have:

    'db'=>array(
                     ...
        'charset' => 'utf8',
    ),

Besides in the registers of my DB I use "varchar(100) utf8_general_ci". In the document main.php I also have:

return array(
'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
'name'=>'Prueba',
'language'=>'es',
'sourceLanguage'=>'en',
'charset'=>'utf-8',

I am using notepad++ to edit and to create the php documents, and the codification of these documents is UTF-8 sin BOM.

Please, I need your help, I don't know that is my error. Somebody could help me?

Thank you very much.
