   While core TUI BiDi reordering is being developed, you can use the community plugin opencode-rtl (v1.0.0 is now live on npm) to resolve the chat response and BiDi isolation issues:

   // opencode.jsonc (OpenCode 2)
   {
     "plugins": [
       {
         "package": "opencode-rtl",
         "options": {
           "language": "auto"
         }
       }
     ]
   }

   What it handles right now:

   • Unicode BiDi Isolates (RLI / PDI): Wraps RTL prose so terminals with BiDi support (WezTerm, iTerm2, Windows Terminal, Ghostty) render words and sentences in the correct visual order.
   • Mixed Code & Text Protection: Protects inline code blocks, commands, and markdown formatting markers from getting inverted inside RTL sentences.
   • System Prompting: Injects language guidance so the model understands and structures RTL output properly.
   • Multi-language Support: Automatically detects Kurdish, Persian, Arabic, Hebrew, Urdu, and other RTL scripts.
