A concrete starting point
Count single-line logical columns using fixed tab stops and one column per other Unicode code point. Check consecutive tabs and an emoji, rejecting zero-width stops and line breaks rather than reporting terminal display width.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
