Is some Unicode characters work, and some don't then it sounds like an
Emacs bug decoding or SBCL encoding bug to me.

What happens if you write the problematic characters into an UTF-8
encoded file using SBCL, and then try to open it as an UTF-8 file
using Emacs? Can you verify that the contents of the file are as
expected using something other then Emacs or SBCL?
