Fix for mb function overload mb_substr acting different
When bug hunting https://github.com/fabpot/Twig/issues/1428 I ran into an issue.
I started out by changing my `php.ini` for the `cli` enviroment, I've added:
`mbstring.func_overload = 2`
Later I tested with adding and removing:
`mbstring.internal_encoding = 'UTF-8'`
It turns out `mb_substr` returns `false` and not `''` when doing something like this:
```php
$item = '';
$start = -1;
$length = 1;
$charset = 'UTF-8';
$a = mb_substr($item, $start, $length, $charset);
var_dump($a);
die;
```
I'm not sure this will fix 1428 since I don't have enough information for this, but this PR should at least fix one issue.
