⚠️ Common Issues

  • • Copy-paste problems
  • • Database/search issues
  • • Phishing attacks (look-alike URLs)
  • • Content moderation bypassing
  • • Unexpected formatting

Common Mistakes to Avoid

⚠️

Thinking all invisible chars are malicious

Solution: Some are legitimate: U+FEFF (BOM) at file start, zero-width joiners in some languages. Context matters.

⚠️

Not checking for homoglyphs

Solution: This tool finds invisible chars, but lookalike characters (Cyrillic "а" vs Latin "a") need separate tools.

⚠️

Auto-removing all hidden characters

Solution: Some hidden chars are needed (RTL marks in Arabic). Understand what you're removing before cleaning.
