Char to ASCII and back ?

Others have answered the basic question, but I'm puzzled by your
example use case.  What do you mean, "to code a message"?  In
many cases, you would just want to send the string itself... it's
just a sequence of bytes in memory.  For example, if you are doing
socket communication, or talking through a serial port, you don't
do anything special to strings, you just send them as-is.

Or is it really just curiosity, in which case I can shut up again. :-)
