[LISPWORKS][Common Lisp HyperSpec (TM)] [Previous][Up][Next] Invalid Characters

Characters with the constituent trait invalid cannot ever appear in a token except under the control of a single escape character. If an invalid character is encountered while an object is being read, an error of type reader-error is signaled. If an invalid character is preceded by a single escape character, it is treated as an alphabetic[2] constituent instead.
