Locale:...:KOI8_U(3)
okay bestie, welcome to the Locale:...:KOI8_U(3) page from the User Contributed Perl Documentation. The main character here is Locale::RecodeData::KOI8_U, and we’re getting into it 💅
💖 NAME 💖
Locale::RecodeData::KOI8_U — conversion routines for KOI8-U. That’s literally the name, periodt ✨
🌸 SYNOPSIS 🌸
This module is internal to libintl. Do not use directly!
No cap, bestie: it says do not use directly 😭 That’s the whole synopsis vibe.
🦋 DESCRIPTION 🦋
This module is generated, okay? It contains the conversion tables and routines for KOI8-U. Generated content, conversion tables, routines — all of it, mwah 🎀
🎀 COMMENTS 🎀
The following comments have been extracted from the original charmap:
version: 1.1
source: RFC 2319
source: http://www.net.ua/KOI8-U/Please note that aliases listed above are not necessarily valid! 🙈
👑 CHARACTER TABLE 👑
The following table is sorted in the same order as the original charmap. All character codes are in hexadecimal. Please read 'ISO-10646' as 'ISO-10646-UCS4'. ✨
Local | ISO-10646 | Description
-------+-----------+-------------------------------------------------okay bestie, the moment we've all been waiting for — the actual byte-by-byte glow-up of KOI8_U. Three columns, no filler: the local byte, the ISO-10646 code point it maps to, and what that character actually is. Read it like a group chat roster: everybody's here, nobody's left out. 💅
💀 The control characters, a.k.a. the OGs (0x00–0x1F)
These are the ancient ones. They don't look like anything, they do things — beep, back up, feed a line. Respect them.

🎀 Box drawing era, activate (0x80–0x92)
Bestie. This is the part that makes KOI8_U iconic. Rows and columns and corners, all done with light strokes. It's giving "I made the whole terminal UI myself." 🌈

Math symbols, a bullet, a non-breaking space, a degree sign, a superscript two, a middle dot, and a division sign. Truly a mixed bag but honestly? Every one of them served.

9F | 000000F7 | DIVISION SIGNquick heads-up, bestie: that 9A is NO-BREAK SPACE — it looks like a space, it is not the 20 SPACE. Don't let it gaslight you. 🙈
🦋 Double-line box drawing + the Ukrainian letters show up (0xA0–0xBF)
Now the box drawing levels up to double strokes, and the Cyrillic starts sliding in between the corners — IO, UKRAINIAN IE, BYELORUSSIAN-UKRAINIAN I, YI, and the GHE WITH UPTURN. This is the good stuff. ✨

That's how the table reads — don't "fix" it, just know it. 😭
also BF = COPYRIGHT SIGN?? nestled right at the end of the box drawing section?? slay placement honestly. ©️💅

okay and that's the whole table, bestie, you made it to FF 🎉 ngl the ordering gets a lil feral near the end (F1 just casually jumping to YA, and F6/F7 going back to 00000416 and 00000412) — that's just how the data is laid out, I don't make the rules, I just report them 💀 copy it exactly and you're golden.
