Why ChatGPT Adds Hidden Characters

When copying text from ChatGPT, invisible Unicode characters like zero-width spaces (U+200B), non-breaking spaces (U+00A0), and hidden formatting marks can be inserted without you noticing. These characters may break JSON, cause code syntax errors, or trigger validation failures.

Common Problems After Copying

  • JSON parse errors or invalid token warnings
  • "Unexpected token" errors in JavaScript
  • Code compilation failures after pasting
  • Broken database inserts and API validation failures
