No. SBCL has detected your terminal doesn't support the characters
you're trying to print, so, it's generating an error.  As you can see
a few lines higher up, the standard output file has an associated
encoding of ASCII, meaning that probably the output of 'locale' on
your system contains LANG=POSIX or LANG=C.
