Description:
------------
mb_convert_case with MB_CASE_TITLE capitalises the 's' after an apostrophe. It could also optionally accept an array of words not to change, such as 'a', 'at', 'in', 'of', etc.

Reproduce code:
---------------
<?php
print mb_convert_case("THE APOSTROPHE'S 'S' SHOULD NOT BE CAPITALISED", MB_CASE_TITLE);
?>

Expected result:
----------------
The Apostrophe's 'S' Should Not Be Capitalised

Actual result:
--------------
The Apostrophe'S 'S' Should Not Be Capitalised

The bug as originally reported was fixed in https://bugs.php.net/bug.php?id=46626

Capitalising the 'th' in 5th is a slightly different issue, and is still present in PHP 7.1.0-dev

I would suggest the title of this bug is updated.

As discussed in bug #65544, the behavior regarding "5th" is consistent with both the old and the new title-casing algorithms specified by Unicode, so I'm going to mark this as Won't Fix.
