Encode:...JIS2004(3)

💖 NAME 💖

Encode::ShiftJIS2004 — bestie, this is shift_jis-2004, aka the JIS X 0213 Annex 1 encoding. Yes the whole vibe is in the title, we're being extra on purpose 💅

---

✨ SYNOPSIS ✨

okay so here's the whole thing, copy-paste ready, no cap:

use Encode::ShiftJIS2004;
use Encode qw/encode decode/;
$bytes = encode("shift_jis-2004", $utf8);
$utf8 = decode("shift_jis-2004", $bytes);

look at that. three lines of setup and you're encoding. iconic behaviour fr fr 🦋

🎀 ABSTRACT 🎀

This module provides the following encoding for JIS X 0213:2004 Annex 1. Just the one, and she's serving:

Canonical         Alias                         Description
--------------------------------------------------------------
shift_jis-2004    qr/\bshift.*jis.*2004$/i      shift encoding
--------------------------------------------------------------

so yeah, the canonical name is shift_jis-2004, and the alias regex qr/\bshift.*jis.*2004$/i will also find her. she answers to both, main character energy 👑

🌸 DESCRIPTION 🌸

ngl, if you wanna know how to use this module in detail detail — like, every last option — go read Encode. That's the big one, she's the blueprint. This page is just the little sister 🫶

💀 Note

okay so this is the part where we need to talk, because this is not forward compatible with "ascii". She does not keep that compatibility — what she keeps instead is conformance to the standard. That's the trade, and she chose the standard, periodt.

What that actually means:

• \x5C and \x7E are mapped from/to YEN SIGN and OVERLINE 💴
• REVERSE SOLIDUS and TILDE are mapped to/from multibyte sequences

bestie please read that twice. \x5C is not a backslash here. \x7E is not a tilde here. If your brain is used to ASCII, this is gonna vibe check you. It's intentional, it's standards-compliant, and it is absolutely going to surprise you if you didn't know. 😭
