Decode and encode HTML character entities. Method based on code obtained from: http://www.thinkmac.co.uk/blog/2005/05/removing-entities-from-html-in-cocoa.html (blogpost no longer available)
There are just two methods, which should be very self explanatory:
- (NSString *)kv_decodeHTMLCharacterEntities;
- (NSString *)kv_encodeHTMLCharacterEntities;
