multi-byte awareness for formatted_print.c

Hi, I was wondering if there are any plans to mutli-byte enable the formatted print family of functions in formatted_print.c? The reason that I ask is that I have just run into a case where it incorrectly deals with a % sign in some multi-byte text. A possible solution might be to code a generic multibyte string walking function in the mb_string extension that, given a point to a multi-byte string, returns the wide character at the current position and advances the pointer to the next wide-character. I think there is such a function in multi-byte aware libc, but that's not always available, so I suggest an implementation in mbstring. I've already written some code that effectively does this in html.c for htmlentities and htmlspecialchars. Any comments/suggestions? --Wez.
