Letters delete whole post - Example: " ? "

[TheEliteGaming]

Hey, I have had this problem from beginning on.

When ever someone writes a message with ascii letters or even the ? symbol it deletes the post.

Example:

Hello, this is my post.

I will keep typing but first ??????? Test

So how are you today?

The output (actual post):

Hello, this is my post.

I will keep typing but first

This is really pissing me off and a pain in the ass, even the currency (Pound) does the same....

I really need help
