[pro] write-char vs. 8-bit bytes

[Paul Tarvydas]

I'm using sbcl to write-char a 16-bit unsigned integer to a socket as 
two separate unsigned 8-bit bytes, for example 141 should appear as

#x00 #x8d.

SBCL appears to convert the #x8d into a two-byte utf-8 char, resulting 
in 3 bytes written to the stream

\#x00 #xcd #x8d.

What is the proper incantation to achieve this?  (SBCL on Windows, if 
that matters).

thanks
