Web authors have come to depend on HTML entities (those strings that begin with & and end with 😉 to represent special characters (from ISO 8859-1 Latin-1). Microsoft Internet Explorer supports the trademark character through the “™” entity, but be aware of what browser your audience is using before you rely on ™, as your page will display ™ rather than ? on other browsers. An alternative way to display TM is:
Yet Another TrademarkTM
which appears as:
Yet Another TrademarkTM
