# Solving Unicode Character Warning for Crossed Swords Symbol (⚔)

## Problem
The character with Unicode value \u2694 (crossed swords ⚔) was not found in the [LiberationSans SDF] font asset, causing it to be replaced with a square placeholder (□).

## Solution Options

### Option 1: Add Fallback Font (Recommended)
1. **Download a Unicode Symbol Font:**
   - Use Noto Color Emoji font from Google Fonts
   - Use Segoe UI Symbol (Windows system font)
   - Use Arial Unicode MS

2. **Import Font into Unity:**
   - Place font file in `Assets/Fonts/` directory
   - Select the font in Project window
   - In Inspector, set Font Size: 512, Sampling Point Size: Auto, Padding: 5
   - Click "Generate Font Atlas"

3. **Set up Fallback Font:**
   - Open Window → TextMeshPro → Font Asset Creator
   - Create a new TMP font asset from your symbol font
   - Include Unicode range: 0x2600-0x26FF (Miscellaneous Symbols)
   - Generate the font atlas

4. **Configure Fallback in TMP Settings:**
   - Go to Edit → Project Settings → TextMeshPro → Settings
   - In "Fallback Font Assets" list, add your new symbol font
   - OR directly assign to specific text components

### Option 2: Use Alternative Characters
Replace the crossed swords symbol with text alternatives:
- "⚔" → "X" or "VS" or "v"
- "⚔" → "[COMBAT]" or "BATTLE"
- Use TextMeshPro rich text: `<sprite name="sword">` if you have sprite assets

### Option 3: Create Custom Font Atlas
1. Use FontForge or similar tool to add the missing character to LiberationSans
2. Or create a comprehensive font that includes all needed symbols

### Option 4: Use Sprite Assets Instead
1. Create a sprite image of crossed swords
2. Import as TMP Sprite Asset
3. Use `<sprite="crossed_swords">` in text instead of Unicode character

## Implementation Steps for Option 1:

### Step 1: Download Noto Emoji Font
```bash
# Download from Google Fonts or use system fonts
# Windows: C:\Windows\Fonts\seguisym.ttf (Segoe UI Symbol)
```

### Step 2: Create TMP Font Asset
1. Window → TextMeshPro → Font Asset Creator
2. Source Font File: Select your symbol font
3. Sampling Point Size: Auto Sizing
4. Character Set: Unicode Range
5. Character Sequence (Hex): 2600-26FF
6. Render Mode: SDFAA
7. Generate Font Atlas

### Step 3: Configure Fallback
Add to TMP Settings or assign directly to text components that need symbols.

## Quick Fix for Development
If you want a quick temporary fix, you can replace the character in your code:

```csharp
// Replace crossed swords with alternative
string text = originalText.Replace("⚔", "[X]");
// or
string text = originalText.Replace("\u2694", "VS");
```

## Finding the Source
To find where this character is being used, search your project for:
- "⚔" (the actual character)
- "\u2694" (Unicode escape)
- Any text files or scripts that might be setting this character

The warning indicates it's in a text object named "Title", so check:
- UI elements named "Title"
- TextMeshPro components in your scenes
- Dynamic text setting in scripts

This should resolve the Unicode character warning and properly display symbols in your game.
