Using default_charset for htmlspecialchars() and others

I am not sure if this has been discussed or not. I will gladly make an RFC if not. I think it would be very intuitive if htmlspecialchars used the ini value default_charset as its default. And any function that takes an optional character set. A) Has this been discussed? B) If not, do others think it is worth of a proper RFC? There would be some BC breakage for sure as the default behavior would be changing. -- Brian. -------- brianlmoon@php.net
