When you write the data to the socket, all data are converted from the CPU 
endianness (little endian for Intel/AMD) to the network endianness (big endian 
by definition).

When you read the data from the socket, the data must be converted back from 
big endian to little endian, and it is done automatically by READ.

But if you read everything inside a string, that is not done, because string 
are bytes, and so do not have endianness.

Do you have an example of code that takes the socket data from a big message 
like you described and decode it?

We will find a solution!
