Ok, never mind - I answered my own question.

I'm still learning CL (after 18 months...) and I just discovered the method (stream-external-format...) which lets me find out what I need to know.

When I output such text to the REPL (using slime or ccl directly in a terminal) the characters show up fine. However, when I write the same text to a file, and then look at the file emacs or using more in a terminal, the accented characters are wrong: you know, line noise.
