It uses JavaScript's String.length, which counts UTF-16 code units. ASCII and Latin text count as you'd expect; emoji and some CJK characters may add 2 to the count due to surrogate pairs.
No - empty lines are excluded from the 'shortest line' calculation, otherwise the answer would always be 0. The longest result includes every non-empty line.
The tool reports the count of ties and shows the first match. For example, if three lines all share the maximum length, you'll see 'Longest: 3 lines tied at 142 chars'.
Word mode splits on any whitespace (spaces, tabs, newlines). Punctuation stays attached - 'don't' counts as one 5-character word, not two.
Optimize your content structure and ensure your data fits within specified bounds with this efficient Find Longest / Shortest Line tool.
