Like I said, the PHP ctype functions are just thin wrappers over the underlying system's ctype functions. Like many other things in PHP, we are just a thin shell on top of basic system capabilities. Whatever restrictions apply to the underlying system will apply to the PHP functions. And, it works for some people because those people passed in the single-byte ISO-8859 pound character whereas for the non-working version you are passing in the 2-byte UTF-8 character. -Rasmus
