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

# 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:

// 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.
