Forget about the C code, what about the memory? A 1000 byte file
requires 2000 bytes of memory in a unicode representation. If
each character required 32 bits or memory, a 1 meg file would
require 4 megs of system memory. That is just crazy!

Don't forget about the network transfer time either. Why would
anyone want to transfer 'a' as a 32 bit number over a network?

Using UTF-8 is a great solution since existing 8 bits
character sets require only 8 bits of system memory
to store them.
