spaces aren't parsed when next to an entity

[Coeur]

We can't parse correctly:
<tag>I love &apos;entities&apos; in a string</tag>

As it will result in:
tag->@"I love'entities'in a string"

Instead of:
tag->@"I love 'entities' in a string"

Parsing any entity like &apos; will strip the leading and trailing space characters. It will even strip any entity used to represent a space character, such as: &#x9; &#9; &#xA; &#10; &#xD; &#13; &#x20; &#32; &#x85; &#133;
