charnames and CJK

Cool, we get CJK (quasi-)names now.

    % perl5.12.3 -Mcharnames=:full -E 'say charnames::viacode(0x547c) || "<missing>"'
    <missing>
    %# blead -Mcharnames=:full -E 'say charnames::viacode(0x547c) || "<missing>"'
    CJK UNIFIED IDEOGRAPH-547C

    % perl -Mcharnames=:full -wE 'printf "U+%X\n", ord "\N{CJK UNIFIED IDEOGRAPH-547C}"'
    Unknown charname 'CJK UNIFIED IDEOGRAPH-547C' at /usr/local/lib/perl5/5.12.3/unicore/Name.pl line 1
    U+FFFD
    % blead -Mcharnames=:full -wE 'printf "U+%X\n", ord "\N{CJK UNIFIED IDEOGRAPH-547C}"'
    U+547C

It's not a new code point at all:

    % blead uniprops -a 'CJK UNIFIED IDEOGRAPH-547C' 
    U+547C ‹呼› \N{CJK UNIFIED IDEOGRAPH-547C}

Since it was already here in 1.1, I figure charnames just acts
differently now.  Is that right?
