How do you define what can and cannot be fixed, though? You'd have to
know the "bad" characters and in that case, a simple str_replace() is
all you need.
$bad_characters = array('^','*','#');
$text = str_replace($bad_characters,'',$text);
$text = htmlentities($text);
Or, since you don't really know what's "bad" then you'd want to define
what's good. You could use get_html_translation_table() to find
everything that htmlentities() will convert and then combine those
characters, alphanumeric characters and whitespace into a preg_replace
to match anything that's *not* one of those characters and erase it.
