This usage is useful only for -S mode. The recent Asian codecs
register its aliases by their respective .pth. So, backporting
CJK codecs won't let Japanese developers code in this way.
If there's a man who need real JapaneseCodecs not CJK codecs,
they can use it by installing JapaneseCodecs package as they've
been done.
