When do you use U+2024 ONE DOT LEADER instead of U+002E FULL STOP? Is there a difference of appearance in high quality typesetting? - Karl
There seems to be a difference: leaders are expected to be written in sequences (sometimes long) to create a dotted line. The complete sequence of leaders then seems to be a form of tabulation (sort of whitespacing), and default ignorable, unlike the full stop which is a non ignorable punctuation (or a non ignorable decimal separator).
Also the sequence of 3 one-dot leaders is not completely an ellipsis punctuation, because many typesettings include a tiny space after the ellipsis (or after the full dot), this thin space being absent from the isolated leader.
why is it not categorised as white space then? or is it? doesn't look like it is to me, but i'm not sure how to actually find out for sure.
