To demonstrate a QR Generator issue in a forum, use harmless text or an example-domain URL. State the exact input payload, output dimensions, error-correction setting if exposed, and decoded result from an independent scanner. Do not post live payment, access, or sign-in codes; a QR image may carry actionable secrets. If the bug concerns special characters or long URLs, preserve those features in a synthetic payload. That makes the report reproducible without exposing a real destination.
