How correct validate data from user to save in database from inputs?

I use this for textfields:

        $name = trim(sanitize_text_field($_POST['name']));

But if i add special signs like "&*({} Something like this ^&({}<>", then they add without a problem.

I need add only "Something like this" without special signs.
