Subject: Bumped CodeIgniter's PHP requirement to 5.2.4. Yes I know PHP 5.4
 just came out, and yes I know PHP 5.3 has lovely features, but there are
 plenty of corporate systems running on CodeIgniter and PHP 5.3 still is not
 widely supported enough. CodeIgniter is great for distributed applications,
 and this is the highest we can reasonably go without breaking support. PHP
 5.3 will most likely happen in another year or so. Fingers crossed on that
 one anyway...

Subject: character_limiter now works correct for UTF-8 strings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

strlen() doesn't return the actual length for unicode strings. For example strlen('سلام') returns 8, but length of سلام is 4. strlen(utf8_decode('سلام')) returns correct value 4.
Reference: http://www.php.net/manual/de/function.strlen.php#45407
