Perl Encode Hackers,
I have been annoyed by the fact that Encode::JP is yet to support
JISX0212-1990. Though this charset is hardly used, this is official
part of euc-jp today as well as iso-2022-jp. Without it, euc-jp support
is hardly complete.
Desperately I reviewed Nick's compile implementation once again and
found that there is no reason compile cannot handle 3-byte code. "Oh
man!" I shouted, because JIXX0212 in euc-jp is represented as 3-byte,
0x8F + (jisx0212 & 0x8080).
I have created a ucm file called euc-jp+0212.ucm that looks like this;
> diff -u Encode/euc-jp.ucm Encode/euc-jp+0212.ucm | less

That is,
* <mb_cur_max> is now 3, instead of 2
* \x8F is no longer control character, but the first byte of 3-byte
represented jisx0212.
* The rest of table I have grabbed out of Jcode (Jcode/Unicode/table.h)
and modified JP/Makefile.PL so it uses new table. Voila! It worked!
Since Encode/JP/JIS.pm and Encode/JP/ISO_2022_JP is already coded to
handle jisx0212 (if euc-jp supports that), it automagically adds
jisx0212 support to other encodings as well
I need to fix pod and t/JP.t so it tests 0212 part but I will upload
new Encode package within 24 hours.
Thank you Nick for making compile this smart!
