In specific conditions, objects listed in the sub-items list of the Administration Interface will display a blank title/name, and only the content type icon.
This is caused by a non-multibyte-aware clamp on the title's length - in a situation where a string is composed of both single and multi-byte characters, the clamp operation may cause an invalid character to be included in the title, which, when passed through htmlentities, yields an empty string:
Steps to reproduce:
1 - Create a class with a title attribute longer than 255 characters (i.e, modify the Article class)
2 - Create a new content for this object with a string combining both multi and single byte characters, i.e:
3 - Verify that, in the sub-items list in the admin interface, the name for this object is blank.
