title: Unserialize offset error, string length seems too long
body: <p>I am trying to unserialize a longtext (utf8_unicode_ci) from a database query, but when I do I get the following error.</p>
  
  <pre><code>unserialize(): Error at offset 6 of 737 bytes
  </code></pre>
  
  <p>I guessed that my string was invalid so I outputted it to the browser. I noticed the string length was a little longer then what it was actually supposed to be. When I copy and paste the output in the browser and hard code it into the php the sting length changes to a smaller one and the unserialize works.</p>
  
  <p>Database string...</p>
  
  <pre><code>ASCII - string(737) "a:10:{s:2:"id";i:2234950;s:13:"full_describe";s:11:"Brace start";s:6:"person";s:17:"Dr Aalok Y Shukla";s:8:"datetime";s:25:"2014-01-06T09:00:00+00:00";s:8:"duration";i:30;s:11:"on_waitlist";b:0;s:10:"company_id";s:5:"35927";s:8:"attended";b:1;s:6:"_links";a:2:{s:4:"self";a:1:{s:4:"href";s:60:"http://uk.bookingbug.com/api/v1/admin/35927/bookings/2234950";}s:6:"client";a:1:{s:4:"href";s:57:"http://uk.bookingbug.com/api/v1/admin/35927/client/809828";}}s:11:"appointment";a:1:{s:11:"description";s:11:"Brace start";}}"

  <p>Copied and pasted string into php...</p>

  <p>As you can see the strings are the same but the string from the database call shows the offset error.</p>
  
  <p>Do I need to do some sort of decoding or formatting on the string returned from the database?</p>
  
  <p>Thanks</p>
