reading udp enc28j60

hi folks i'm using an arduino nano with enc28j60 ethernet shield, I have the following sketch up and running but need to read the data in a different format, I also have an arduino uno with a wiznet 5100 using the ethernet library but that isnt supported on the enc28j60.

Aaaaanyway long story short i have a char array in the uno sketch that gets populated via UDP and that i ll working fine, the problem I get is when i read the values in the data in the uno array is completely different to the array Ethernet::buffer in the nano sketch (shown below)

in the uno i create a char array and use udp.read to populate the array, how would I get the ame results in the sketch below?

// Demonstrates usage of the new udpServer feature.
//You can register the same function to multiple ports, and multiple functions to the same port.
