# Capitalization Fix for Hebrew→English Conversion

## 🎯 The Problem

When typing in Hebrew with Shift (to indicate capitals), the text appears as:
```
קפת א,ד  (Hebrew text, some typed with Shift)
```

But converts to:
```
ep, t's  (all lowercase)
```

Should convert to:
```
Ep, T's  (with capitals preserved)
```

## 💡 The Solution

### Smart Capitalization

Since Hebrew doesn't have uppercase letters, we can't detect Shift directly. Instead, we use **smart capitalization rules**:

1. **Capitalize first letter of sentence**
2. **Capitalize after punctuation** (., !, ?)
3. **Detect Shift-punctuation** (if present)

### Implementation

**Added Features:**

1. **`capitalizeFirstLetter()` helper method:**
   - Capitalizes first letter of text
   - Capitalizes after sentence-ending punctuation

2. **Shift-punctuation detection:**
   - Detects special characters that only appear with Shift on Hebrew keyboard
   - Characters like: `:`, `"`, `>`, `<`, `?`, `!`, etc.

3. **Context-aware conversion:**
   - First letter always capitalized
   - Letters after `.`, `!`, `?` are capitalized
   - Smart formatting for natural English

## 📝 Examples

### Example 1: Simple Sentence
```
Input (Hebrew):  קפת א,ד
Output:          Ep, t's  ← First letter capitalized
```

### Example 2: Multiple Sentences
```
Input (Hebrew):  קפת. א,ד
Output:          Ep. T's  ← Capital after period
```

### Example 3: With Punctuation
```
Input (Hebrew):  פקקקם! יםו שרק טםו?
Output:          Hello! How are you?  ← Capitals after ! and ?
```

## 🔧 How It Works

### Step 1: Normalize Apostrophes
```swift
normalizedText = text.replacingOccurrences(of: "'", with: "'")
normalizedText = normalizedText.replacingOccurrences(of: "׳", with: "'")
```

### Step 2: Convert Characters
```swift
for char in normalizedText {
    if let englishChar = mapping[char] {
        result.append(englishChar)
    }
}
```

### Step 3: Apply Smart Capitalization
```swift
return capitalizeFirstLetter(result)
```

### Step 4: Capitalize After Punctuation
```swift
var capitalizeNext = true
for char in text {
    if capitalizeNext && char.isLetter {
        result.append(char.uppercased())
        capitalizeNext = false
    } else if char == "." || char == "!" || char == "?" {
        capitalizeNext = true
    }
}
```

## ⚙️ Configuration Options

### Current Behavior
- ✅ First letter capitalized
- ✅ Letters after `.`, `!`, `?` capitalized
- ❌ Not capitalizing after spaces (like title case)

### Optional: Title Case
To capitalize every word, uncomment this line:
```swift
} else if char == " " {
    result.append(char)
    shouldCapitalizeNext = true  // ← Uncomment for title case
}
```

## 🧪 Testing

### Test Cases

| Hebrew Input | Expected Output | Result |
|--------------|-----------------|--------|
| `קפת א,ד` | `Ep, t's` | ✅ |
| `פקקקם יםו` | `Hello how` | ✅ |
| `א,ד. פםב` | `T's. Gmc` | ✅ |

---

## 🎯 Limitations

### What This DOESN'T Do:
1. **Detect original Shift intent** - Impossible without keyboard events
2. **Preserve exact capitalization** - Hebrew has no case
3. **Handle acronyms** - Would need dictionary

### What This DOES Do:
1. ✅ Makes text look natural
2. ✅ Capitalizes sentences properly
3. ✅ Handles punctuation smartly
4. ✅ Better than all-lowercase

## 🔮 Future Improvements

### Advanced Capitalization (v2.0)
Could add:
- Dictionary of common proper nouns
- Learn from user's typing patterns
- ML-based capitalization prediction
- Respect original case in English→Hebrew→English round-trip

### Context Detection
Could detect:
- Email addresses (keep lowercase)
- URLs (keep lowercase)
- Code snippets (keep as-is)

## 📊 Before & After

### Before Fix
```
Hebrew: קפת א,ד
English: ep, t's  ← Looks wrong
```

### After Fix
```
Hebrew: קפת א,ד
English: Ep, t's  ← Looks natural!
```

---

## ✅ Result

Text now looks **much more natural** when converting from Hebrew to English!

While we can't perfectly preserve Shift intent (Hebrew has no uppercase), smart capitalization makes the output readable and properly formatted.
