Note the `strlen`: it is not correct to use here, strdisplaywidth() is. Note about strchars(): it is not correct because it counts composing characters separately and does not respect fullwidth characters. > > Thanks, that should be an easy update.

At least not if I can avoid it. Tables cause huge performance issues in some browsers if they get to be several thousand rows long; and I do on occasion convert entire files this many lines. > > > > > > > 3. Sometimes line does not contain highlighting with g:html_no_pre=0: http://img-fotki.yandex.ru/get/9485/9151298.3/0_9e206_c721f0d3_orig.png(3.png): guess this is because it ends with concealed character. > > > > > > I haven't noticed this; I'll need to look into that.

There is a reason for my formatvim using table with one table row per one line, even though it is very imperfect: too tall characters cause shift: http://img-fotki.yandex.ru/get/9264/9151298.3/0_9e208_cb2ab30c_orig.png(4.png). This is not the first tall character here and diff is thus incorrect. Also note thin black gaps between lines. > > > > > > I struggled with a similar thin gaps problem for a LONG time before I gave up. As mentioned, I *really* don't want to resort to a table. I would love to find a better solution to that. Please anybody let me know if you have any ideas. Design constraint is that TOhtml (mostly) builds one whole line at a time.
The problem here is not gaps, they are standable. In fact, I have gaps problem with these characters too, though it is different gaps problem (gap between input with sign or line number and adjacent lines). The real problem is incorrect diff, and this is not. Such characters are uncommon (problem should be observed in case font that browser chose does not have required characters), but e.g. powerline has some. In some fonts characters I use for fold markers are absent (I use unicode black triangles: BLACK RIGHT-POINTING TRIANGLE (U+25B6) and BLACK UP-POINTING TRIANGLE (U+25B2)). Note the solution I use: record all non-header and non-footer lines into a list: one list for each buffer; and then merge lines adding start, end and separator, adding header and footer only then. This is a workaround for design constraint. It is also a reason I had to add tilde lines I mentioned previously: you MUST have lines with equal lengths if you use this solution. I may as well have switched to using container div's or anything else that will allow keeping diff correct under such circumstances, but table is the only solution I know. Well, I can imagine a few based on JS, but I am not up to using it without user request. > > > > 5.

The problem is that line does "windo | if ...." when it should be "windo if ...." (without the |).
