Arabic Chat Fix

Type Arabic in R.E.P.O.'s chat and have it show up connected (proper joined letters) and in the correct right-to-left order — instead of the broken, disconnected, reversed text you normally get.

Best part: it works for everyone in the lobby, even players who don't have the mod.

Why it works for people without the mod

Normally Arabic needs a "shaping" step to join letters and a "bidi" step to lay them right-to-left. R.E.P.O.'s chat doesn't do either, so you get isolated, reversed letters.

When you send a message, this mod converts your Arabic into its final presentation-form glyphs (the already-joined shapes) and puts them in visual order before the message goes out over the network. The text that travels to everyone else is already "baked," so even a player with no mod — whose game does no shaping at all — draws it correctly. There's nothing left to shape.

So:

You type normally. While typing you'll still see the raw letters (that's just the live input box). On send, it's fixed for everyone.
People without the mod see your Arabic correctly. ✅
People with the mod also see correct Arabic, and can additionally read raw Arabic typed by non-modded players (local display fix).

Install

Use a mod manager (Thunderstore / r2modman / Gale): just click install. It pulls in BepInEx automatically.

Manual install:

Install BepInExPack into your game folder.
Drop ArabicRepo.dll into R.E.P.O./BepInEx/plugins/.
Launch once to generate the config.

Configuration

Config file: BepInEx/config/bandar.arabicrepo.cfg

FixOutgoing (default true) — bake your typed Arabic on send so everyone sees it.
FixIncomingDisplay (default true) — locally reshape raw Arabic typed by players without the mod, so you can read them.
CombineAllahLigature (default true) — render the standalone word الله as the single ﷲ glyph.
KeepLatinAndNumbersInOrder (default true) — keep Latin words, numbers, emails and URLs in normal reading order inside Arabic text.

Advanced (only needed if a game update moves things around):

ChatTypeName, SendMethodOverride, MessageFieldOverride, AggressiveAutoHook, DumpChatClassToLog.

Because R.E.P.O. updates often and renames internals, the chat hook is found at runtime instead of hard-coded. If a future update breaks sending, set DumpChatClassToLog = true, open BepInEx/LogOutput.log, find the method that runs when you press Enter, and put its name in SendMethodOverride. That's the whole fix.

Known limitations

The live input box still shows unshaped letters while you type — only the sent message is converted. This is expected.
Full Unicode bidi for deeply mixed/nested text isn't implemented; everyday chat (Arabic, numbers, Latin words, emails, URLs, times) is handled correctly.
Harakat/tashkeel are preserved but some renderers position them loosely.
