ctype functions going, going, gone?

Hi all! I am preparing a Server Side Scripting (using PHP) course for the Web Standards Project Interact[1]. As I am going through security considerations I note that the ctype functions are being used in the manual[2] and have not been deprecated in 5.3. I have, however, been told that they are not, nor ever will be, Unicode compatible.[3] If that indeed is the case: A. Should they not be deprecated formally, including giving an appropriate error when used? (Yes, that will give some people, like me, lots of errors. But I rather take them now than have my code blow up on me in the future.) B. Should not the the manual be telling people about these functions being non-future proof? -- Keryx Web (Lars Gunther) http://keryx.se/ http://twitter.com/itpastorn/ http://itpastorn.blogspot.com/ 1. http://interact.webstandards.org/ 2. http://www.php.net/manual/en/security.filesystem.php 3. http://marc.info/?l=phpdoc&m=119678432606169 P.S. If you are interested in helping us at WaSP make an awesome curriculum for our PHP course, contact me off list.
