Limitations and common mistakes

  • Results reflect your supplied input and selected settings. Check the worked example and output before reuse.
  • Combined input is bounded to 150,000 characters; output text is bounded to 1.2 million characters. Some algorithms impose smaller limits, stated in their error messages.
  • Both inputs must follow their own documented format. Changing direction or mode can require different input; the example is for the displayed settings.
