I find that confusing too. Given the commit log, it is even more
confusing:

- Updated is_string():
   If Unicode semantics is turned on, return "true" for Unicode strings
   only. If Unicode semantics is turned off, return "true" for native
   strings only.

It makes is_string basically useless, I can imagine two solutions:

- keep it and always returns true (unicode and binary strings are 
  strings anyway)

- deprecate it in php 6.0, it will still returns true. At least
  people will know that they should use the new functions

There is maybe a third solution, but certainly too drastic, remove
is_string :)
