Misspelling can't be the reason of problems, unless the value contains
preserved characters (<>& etc.).

To catch these characters, you can apply htmlentities() to transform them
into valid entities; to get rid of control characters, you could write a
simple routine like the following to filter the source text:

function filter($c) {
return ord($c[0]) <= 126 ? $c[0] : '';
}
$filtered = preg_replace_callback('/./s', 'filter', $unfiltered);

Note that this is just an example and might not be suitable for your needs.
