Unicode Sanitizer

A lightweight PHP tool to detect and remove invisible Unicode characters such as:

• UTF-8 BOM (U+FEFF)
• Zero Width Space (U+200B)
• Zero Width Non-Joiner (U+200C)
• Zero Width Joiner (U+200D)

These characters often cause subtle bugs in PHP, JavaScript, and HTML projects.

🚀 Features

• Detect hidden Unicode characters across your project
• Automatically clean infected files
• Safe for batch processing
• Skips vendor/minified files
• Zero dependencies

---

📦 Files

• finder.php → scans and reports infected files
• resolver.php → cleans files automatically

---

🧪 Usage

1. Scan project

php finder.php

Output example:

INVALID: ./Action/UserCreate.php
INVALID: ./Route/Login.php

Scan complete.
Checked: 120 files
Infected: 8 files

2. Fix all files

php resolver.php

Output example:

FIXED: ./Action/UserCreate.php
FIXED: ./Route/Login.php

Done.
Checked: 120 files
Fixed: 8 files

⚠️ Why This Matters

Invisible Unicode characters can cause:

• "Headers already sent" errors in PHP
• Broken JSON responses
• Session/cookie failures
• Unexpected output before <?php

🛡️ Prevention

VS Code

Set encoding to UTF-8 without BOM:

"files.encoding": "utf8"

Git (optional)

Add .gitattributes:

*.php text working-tree-encoding=UTF-8
*.js text working-tree-encoding=UTF-8
*.html text working-tree-encoding=UTF-8
