That directory path came from ASDF. Are you using ASDF3? I haven't
tried that version level.

If you are storing non-ASCII text, you'll want to ensure that
UFFI knows the encoding format that you are using.

There are limited encoding tests for UFFI in tests/i18n.lisp
and may reveal an issue with ClozureCL v1.9. I haven't used
that version of CCL. 

I'm away at conference, but will try to look at that on the plane
back home. You might also find someone who has identified a
solution on the CCL mail list.
