* Revision:
* 2011-11-10, Ce-Yi Hio:
* - fixed conversion error with a number of capitalized entity characters
*
* Revision:
* 2011-11-10, Rob Reid:
* - changed array format
*
* Revision:
* 2012-09-23, Alex Oss:
* - replaced string concatonation in numEncode with string builder, push and join for peformance with ammendments by Rob Reid
