🕵️Invisible Character & Zero-Width Detector Documentation & Guide
Text & Content
The Invisible Character Detector reveals, counts, and strips zero-width spaces, UTF-8 BOM markers, non-breaking spaces, and hidden Unicode characters that cause mysterious code errors.
📋How to Use This Tool
- Paste Suspicious Text or Code: Paste text copied from websites, PDFs, or formatted documents into the inspection area.
- Click Scan & Clean: Perform regex scans across seven classes of zero-width and invisible Unicode points.
- Review Detection Report: Inspect total hidden characters found broken down by character name and hex codepoint.
- Copy Sanitized Code: Copy the thoroughly sanitized output text free of hidden ghost characters.
⚙️Technical & Algorithmic Details
• Zero-Width Code Points: Detects Zero-Width Space (U+200B), Non-Joiner (U+200C), Joiner (U+200D), and Zero-Width No-Break Space (U+FEFF).
• Byte Order Mark (BOM): Identifies U+FEFF headers at file starts which frequently break JSON parsers and PHP headers.
• Non-Breaking Spaces (U+00A0): Safely converts non-breaking web spaces into standard ASCII spaces (U+0020).
💡Practical Use Cases & Best Practices
- Fixing mysterious JavaScript "Unexpected token" errors caused by zero-width spaces copied from documentation.
- Sanitizing source code copied from PDF tutorials or Google Docs before compilation.
- Cleaning copy-pasted API keys, passwords, and tokens where trailing invisible characters cause auth failures.
