Exclude @ from generated passwords

I noticed my email client turned WP-generated passwords into email links, because they contained a ‘@’ symbol. That’s annoying.

Is there a way to exclude ‘@’ from password generation?

I see the function is here:

function wp_generate_password($length = 12, $special_chars = true) {
	$chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
	if ( $special_chars )
		$chars .= '!@#$%^&*()';

	$password = '';
	for ( $i = 0; $i < $length; $i++ )
		$password .= substr($chars, wp_rand(0, strlen($chars) - 1), 1);
	return $password;
}

So can you turn off the special_chars somewhere in an admin area? Or could I turn ‘true’ to ‘false’?

I’ll remove the @ anyway…
