grapheme_substr from Intl have differing behavior as compared to substr:

var_dump(substr('a', 1, null)); //  string(0) ""`
var_dump(grapheme_substr('a', 1, null)); // bool(false)

It looks like on php 5.x it also produces warning.

This behavior needs to be investigated against other wrappers and corrected if needed.
