There are backward letters in the Character Map, and there are third-party sites that simulate backward typing by creating ASCII compliant Unicode characters (not actually a reversed ASCII letter).
Most "mirror text" and "backwards text" sites just reverse the order of letters.
Backward characters should not be used on WikiAnswers. They could be interpreted as nonsense, and users could be warned or restricted.
