I'd be surprised if this were enough.

The nl_langinfo() call has to do with external-format support, not
Unicode per se -- even in an SBCL build with only 256 characters, it
is important to know whether it is writing to an iso-8859-1 or a utf-8
terminal.

I believe Thomas Burdick and Bruno Haible between them established
that more-or-less everything on Mac OS 10.2 spoke utf-8 by default
(and that there was no good way of finding that out programmatically);
so commenting out the definition and call of nl_langinfo, and
hardwiring utf-8 encoding everywhere, should help.  (I believe there
was also something broken on Mac OS 10.2 with respect to dlopen() --
grovelling constants, maybe?)

Cheers,

Christophe

Replaceing the call to nl_langinfo with a constant "utf-8" worked
here.

SBCL uses its own dlopen emulation on OS X, but the current sources
try to grovel dlopen constants from (nonexistent on 10.2) system
header files.  I sent a patch in October that factors out the dlopen
constants into their own header file, and grovels for that on OS X.
It's here:
