Try changing the > 'ambiwidth' option. > 'ambiwidth' is set to its default of "single" and I use no CJK characters; I think there are no ambiguous-width characters either; but I have a lot of Cyrillic text (this is a Russian-French dictionary, after all) and the problem is most apparent with marks in column 1 (and, of course, on lines that exceed the screen width). See for instance one of my pages, not too long but with some long lines: http://users.skynet.be/antoine.mechelynck/slovarj/ru-fr.06.html — try setting marks a, b, c, etc. at far left of some lines that exceed your screen width, then see what ":marks" displays. Most lines start with <p> and end with </p> which should tel you which ones were truncated.
