# arabic text renders disconnected letters bug

## TL;DR

Fixes Arabic text rendering as isolated, disconnected letters. Ensure the text goes through proper shaping: use a real text element, not a canvas fillText without shaping, and keep RTL direction. Use when Arabic letters appear separated. Not for wrong translations.

## The error

```text
Arabic headline renders as isolated glyphs: each letter disconnected, no ligatures.
```

## Fix it

### Step 1: Check how the text is rendered

```bash
node -e "console.log('canvas fillText without a shaping engine vs a DOM text node')"
```

Expected: You identify the unshaped rendering path.

### Step 2: Route text through the shaping engine

```bash
node -e "console.log('use DOM text, or a canvas library with complex-text shaping enabled')"
```

Expected: The text passes through proper glyph shaping.

### Step 3: Verify with a native speaker screenshot

```bash
node -e "console.log('render and confirm letters connect and ligatures form')"
```

Expected: Arabic renders connected and correct.

## When to use this

- Arabic letters render disconnected
- Text is drawn on canvas without shaping

## When NOT to use this

- The translation is wrong, fix the Arabic copy
- Letters connect but order is wrong, check bidi direction

## Tool and version compatibility

- Browsers with complex text layout
- Canvas 2D without manual shaping

## Variant phrasings

### disconnected only in PDF export

The PDF renderer lacks the shaping engine. Embed a shaped text layer instead.

### disconnected in a game engine

Game text renderers often skip shaping. Add an Arabic shaping pass.

## Why it happens

Arabic letters change shape based on neighbors. Rendering paths that draw glyphs one by one skip the shaping step, so every letter appears in its isolated form.

## Edge cases

- Numbers inside Arabic text need bidi isolation to stay in order
- Some fonts lack the contextual forms entirely
- Testing with Latin-only QA misses this completely
