This tool generates bold and italic text using unicode characters. While the text it generates may look similar to text generated using the HTML <bold> or <em> tags or the CSS attributes `font-weight: bold` or `font-style: italic`, it isn't. You can copy and paste this text into email or use it in your Facebook and Twitter status updates. Bold and italics are often used to emphasize a point. Bold text can also be used to help structure larger bodies of text, for example, to denote a subject, heading, or title.
