Title Special Chars are in ascii

When I send the email if I put a non-alpha in the title, like a ' for example, the email shows that as a #&39;

I'm pretty sure I can fix this using a different sanitizer for the filter_input function but i'm not sure which one...

I used the FILTER_SANITIZE_EMAIL and that worked except it also gets rid of spaces, which is no good if a user puts in a title with more than one word. It seems there's no filter that just strips html tags...

Are you using FILTER_SANITIZE_EMAIL for title ?

It will be good if you paste the code snippets here.

Yeah the FILTER_SANITIZE_EMAIL was the only one I could see that didn't change special chars to ascii.

Here's the code, I changed the filter for title back to string so it would go with the rest of the videos.

    $name = trim(filter_input(INPUT_POST, 'name', FILTER_SANITIZE_STRING));
    $email = trim(filter_input(INPUT_POST, 'email', FILTER_SANITIZE_EMAIL));
    $category = trim(filter_input(INPUT_POST, 'category', FILTER_SANITIZE_STRING));
    $title = trim(filter_input(INPUT_POST, 'title', FILTER_SANITIZE_STRING));
    $format = trim(filter_input(INPUT_POST, 'format', FILTER_SANITIZE_STRING));
    $genre = trim(filter_input(INPUT_POST, 'genre', FILTER_SANITIZE_STRING));
    $year = trim(filter_input(INPUT_POST, 'year', FILTER_SANITIZE_STRING));
    $details = trim(filter_input(INPUT_POST, 'details', FILTER_SANITIZE_SPECIAL_CHARS));

When I entered a ' in the title form the email would come out as #&39, the ascii value.
