Practically nothing. There's a function to index a pike_string, but you don't want to use that in tight loops since it's much more efficient to check the width first and then choose a loop compiled with the right char width. That's why there are so many large macros involved whereever any significant string fiddling is done internally in pike.

Likely. I'm not too well versed in how much of that is handled by the includes.
