Question 1

What does case-insensitive matching do?

Accepted Answer

When case-insensitive is enabled, 'Hello' and 'hello' are treated as duplicates. The first occurrence is kept with its original casing.

Question 2

What does 'trim lines before comparing' do?

Accepted Answer

It strips leading and trailing whitespace from each line before checking for duplicates. Lines that differ only in whitespace are treated as duplicates.

Question 3

Is the original order preserved?
