You have to pass the right :coding-system to CREATE-SERVER like 

  (swank:create-server :coding-system "utf-8-unix")

Or set swank:*coding-system* to that value, e.g. in your ~/.swank.lisp.

Here we see that latin-1 rather than an UTF-8 encoding is actually used
on the server. 

That is because SWANK:*CODING-SYSTEM* defaults to "iso-latin-1-unix".

  -T.
