php – Contact form Textarea Field – Dislike and symbol

I've been testing a new contact form that I've put together, and I've noticed that when I write Y The symbol, symbol and any subsequent text are not sent as part of the email.

e.g.

Writing = & # 39;It is a beautiful and sunny day.& # 39; in the field textarea and sending,
I would receive = & # 39;It's a pretty& # 39;

At this moment I only have a little jQuery so that the field is highlighted in red / green if there are more / less than 3 characters:

$ ("# contact_text"). blur (function () {
if ($ (this) .val (). length <3) {
$ ("# contact_text"). css ("border", "solid 1px # D295B5");
} else {
$ ("# contact_text"). css ("border", "solid 1px # DADB93");
}
});
});

But I'm not sure how I'm going to fix this Y problem.

Any help would be greatly appreciated.
