Insert ASCII Control Characters via TinyMCE?

Is it possible to insert ASCII Control Characters into a WYSIWYG editor like TinyMCE?

From what I understand, keyboards usually don't have a key for control characters like SOH (though CR, DEL etc have keys). If it exists also shouldn't it to do some action and not create a Content? You can probably speficy an special sequence using \ but that depends on the program to which you feed it. From an input perspective it is still readable ASCII characters. Also clipboards like that of Notepad gives a Text variant and that should ideally never contain Control Characters.

I am debug and see how SOH came to our Database and if there is a possiblity that Web Forms especiall TinyMCE can get this from the end user.
