RTL

A PocketMine-MP plugin that corrects reversed RTL text in Minecraft: Bedrock Edition.

Bedrock renders Right-To-Left scripts with their characters reversed.

This plugin works around it by pre-reversing the text on the server.

What it fixes

Chat UI and signs only.

• Chat messages (player chat, /say, /tell, tips, popups, system messages, announcements)
• Sign text edited by players

Form UIs, name tags, boss bars, books, scoreboards, titles, and toasts are not handled.

How it works

Hooks into DataPacketSendEvent (chat, tips, popups, system messages) and SignChangeEvent (signs). For each text containing RTL characters:

1. Finds all RTL segments
2. Reverses characters in each segment (cancels Bedrock's char reversal)
3. Reverses their order (cancels Bedrock's swap around LTR words)

Non-RTL text is untouched.

Supported scripts

Arabic (incl. Kurdish, Pashto, Persian, Sindhi, Urdu), Hebrew (incl. Yiddish), Syriac, Thaana, NKo, Samaritan, Mandaic.

Limitations

• Chat input box — text appears reversed while typing. Server can't access the input box.
• Hindi/Thai/Tibetan — these need a text shaping engine (HarfBuzz) that Bedrock lacks. Unfixable server-side.
• Multi-line wrapping — long messages may have lines in reverse order. Depends on client screen size.
