Troubleshooting
The page becomes slow with a large input or repeat count.
Reduce the input, split the operation into smaller batches and close other memory-heavy tabs. Keep an original copy before retrying.
The result changes after I paste it elsewhere.
Test the destination app, font and character encoding. Some apps normalize whitespace or render Unicode differently.
