The attributed string to examine.
An immutable string containing the characters from
NULL if there was a problem creating the object. Ownership follows the The Get Rule.
For performance reasons, the string returned will often be the backing store of the attributed string, and it might therefore change if the attributed string is edited. However, this is an implementation detail, and you should not rely on this behavior.
