Email class Encoding

[eluser]kenjis[/eluser]

Code:

$this->load->library('email');

        $config['charset'] = 'us-ascii';
        $this->email->initialize($config);

        $this->email->from('[email protected]', 'Your Name');
        $this->email->to('[email protected]');

        $this->email->subject('Email Test');
        $this->email->message('Testing the email class.');

        $this->email->send();

The above code sends email with

Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 8bit

But us-ascii must be 7bit.

Is there anyone who knows meaning of "$_base_charsets"?
and why default $_encoding = "8bit" ?

[eluser]ejangi[/eluser]
Not too sure, but my guess is it has something to do with UTF-8??? Just a guess.

Kenjiさん。

$_base_charsets is used to determine which encodings should be considered 7bits - everything else is (erronously) set to 8bits. I'm guessing the $_encoding variable is set to 8-bits because the default encoding is utf-8.

わかった？

Code:

/**

| From the Email library
|
*/
function _get_encoding($return = true)
{        
    $this->_encoding = (!in_array($this->_encoding, $this->_bit_depths)) ? '7bit' : $this->_encoding;

    if (!in_array($this->charset, $this->_base_charsets, TRUE))
        $this->_encoding = "8bit";

    if ($return == true)
        return $this->_encoding;
}

Hi, Armchair Samurai!

My question: "iso-8859-1" is 8bit, isn't it?
