Bug description:Buggy grapheme_substr() on edge case
Description:
------------
See test script below.
The strangest behavior is the difference between a pure ASCII string and an
UTF-8 with chars in the [80-FFFF] range.
The other wrong thing is the difference of behavior between substr() and
grapheme_substr(). I think substr's behavior is the good one.
Test script:
---------------
<?php
var_dump(substr('deja', 1, -4));
var_dump(substr('deja', -1, 0));
var_dump(grapheme_substr('deja', 1, -4));
var_dump(grapheme_substr('deja', -1, 0));
var_dump(grapheme_substr('déjà ', 1, -4));
var_dump(grapheme_substr('déjà ', -1, 0));
?>
Expected result:
----------------
bool(false)
string(0) ""
bool(false)
string(0) ""
bool(false)
string(0) ""
Actual result:
--------------
bool(false)
string(0) ""
bool(false)
string(0) ""
string(5) "éjà "
bool(false)
