Edge Cases
- Very large inputs may take a few seconds to process in the browser. If performance slows, split the input into smaller batches.
- Mixed formatting (tabs, line breaks, or inconsistent delimiters) can affect output. Normalize spacing first if needed.
- Find Duplicate Text Letters follows the selected options strictly. If the output looks unexpected, re-check option settings and input format.
Troubleshooting
- Output looks unchanged: confirm the input contains the pattern this tool modifies and that the correct options are selected.
- Unexpected characters: check for hidden whitespace or encoding issues in the input and try normalizing first.
- Slow processing: reduce input size or try a modern browser with more available memory.
