Huh? What context is this in?

Hi.
I think many line breaks within paragraphs are soft line breaks but
that embedding levels have to be taken into account when deciding the
width of the glyphs; that's as near as I can tell.
Here is the description of the algorithm -- is this what you have read?
http://unicode.org/reports/tr9/
Some rules are in fact applied after the line wrapping (after the soft
breaks) --
"The following rules describe the logical process of finding the
correct display order. As opposed to resolution phases, these rules
act on a per-line basis/and are applied *after* any line wrapping is
applied to the paragraph./
Logically there are the following steps:
* The levels of the text are determined according to the previous rules.
* The characters are shaped into glyphs according to their context
/(taking the embedding levels into account for mirroring)./
* The accumulated widths of those glyphs /(in logical order)/ are
used to determine line breaks.
* For each line, rules L1 <http://unicode.org/reports/tr9/#L1>–L4
<http://unicode.org/reports/tr9/#L4> are used to reorder the
characters on that line."
(I'd have to reread the whole document on line breaking then on bidi
to answer this truely; sorry; hope this helps anyway)
