Subject: Re: Simple characters in the CL Standard From: Erik Naggum <firstname.lastname@example.org> Date: 1998/04/11 Newsgroups: comp.lang.lisp Message-ID: <email@example.com> * Paul Dietz | I have a question for CL Standards gurus: I'll try to answer, anyway. | Is there a standard way in Common Lisp to determine if a character is a | simple character? does (typep <character> 'base-char) cut it? | However, in two lisps I've tried the string containing a single null | character, produced by | | (make-string 1) | or by | (make-string 1 :initial-element (code-char 0)) | | prints as "^@", even with *PRINT-READABLY* set to true. This reads back | in as a two character string (^ and @). do you mean that (length (read-from-string (write-to-string (string (code-char 0)) :readably t))) returns 2, not 1? I can't see that it does that anywhere I try it. what do you do to make the length become 2? #:Erik -- religious cult update in light of new scientific discoveries: "when we cannot go to the comet, the comet must come to us."
