Description:
------------
hi, it is possible to make mb_substr work exactly like substr?

substr("",0,10) // returns false
mb_substr("",0,10) // returns ""

substr("abc",7,1) // returns false
mb_substr("abc",7,1) // returns ""

thank you

This was taken care of in https://bugs.php.net/bug.php?id=28899

If you turn on mbstring.func_overload mb_substr will return false. Otherwise it 
returns ""

Bug #28899 was committed in Rev.#203546

yes but no one uses mbstring overload
in plus it is nearly-always not available on hosts, because it can't be enabled per-dir (read: https://bugs.php.net/bug.php?id=51415)
so i think this should be fixed

Works as designed. The fact substr and mb_substr do not have the same behavior does not mean one of the is wrong. Besides, there would be compatibility issues in changing the behavior of one of them.
