Hi Festus.

If s[0] == 0xfeff, it means you are reading a UTF-16LE string on a 
little-endian system or a UTF-16BE one on a big-endian system. The 
comment "Same as CPU endian. No need to swap bytes." describes that 
If the UTF-16 endian is different from the CPU endian, a BOM will look 
like swapped and s[0] will be 0xfffe.
