Why This Tool?

When copying text from PDFs, web pages, emails, or databases, invisible Unicode characters like zero-width spaces, soft hyphens, or control codes can sneak in and cause:

• Unexpected layout bugs
• Failed string comparisons
• Broken parsing logic
• "Invisible" differences in diffs

This tool instantly reveals what’s really in your string.
