How to do bold and italic text in Facebook chat

I did some research and it turns out you can easily add bold text or italics to your Facebook chat by adding small code around it. I
guess bold text can help emphasize your Facebook chats, and italics can make your text look different. It’s not really a new font for Facebook chat, but it’s kind of cool.
Here’s the code to make your text italic or bold on Facebook chat .:
Bold text – *surround your text with stars*
Italic text – _surround your text with underscore_
Get it?
Put *stars* around your text to bold it,
and
Put _underscores_ to make it italic!
Enjoy your new bold and italic text in Facebook chat!!!
