title: How to show registered Ⓡ or trademark ™ symbol in dialog?
body: <p>I have to show registered Ⓡ and trademark ™ symbol , in the message of an <code>AlertDialog</code>. I set a sting value with the registered and trademark symbol in res/string. But the symbol is shown as a question mark when the dialog opens. How can I correctly show the these symbols in the dialog. Thanks.</p>
