iso-8859-1 and utf-8 are different encodings, you should read your file
in whatever encoding it is. And encoding of the communication between
slime and swank doesn't have anything to do with encoding of files.

Set your slime-net-coding-system to 'utf-8-unix and start clisp with
utf-8, but read your file with
(with-open-file (stream file :external-format charset:iso-8859-1) ...)
