Starting from 5.8.0 Perl comes with encoding support for the CJK languags
(Chinese-Japanese-Korean, CN/JP/KR/TW).  Normally shared libraries are used,
which means that the (relatively large, a few megabytes total) CJK encodings
are loaded on demand (not consuming any memory if the are unused).  However,
if you are building Perl statically, and/or are space-constrained, and
if you are certain you won't be needing CJK support, you may consider
leaving it out.  Note that the CJK support will always be built, but
if you choose not to have it, it will be skipped in the installation phase.

If this doesn't make any sense to you, just accept the default '$dflt'.
