the Cambridge Encyclopedia of Language (p187) defines 3 types:
one where the order of the words within the line is reversed,
a second where the order of the letters within the words is also reversed,
and a third where the glyphs themselves are reversed as well

Perhaps I'm being confused ... it's been a long time ... but I seem to
recall that there are, actually, two types of boustrophedon.
If memory serve me correctly, the older type mirrored the characters on
the right-to-left line, but the newer type didn't, although the line
was, nonetheless, written from right to left.
But I may well be wrong.

Not considering bustrophaedon,
even in the described standard behaviour of OH of having the
characters mirrored when overriden LTR, I believe it is problematic
that one has to replace the punctuation characters.
Usually one would think of the LTR and RTL in OH as the same text with
the same information, ie. the same string of characteres, only
displayed differently (i.e. other text-flow direction, and mirrored).
So why do we have to use other characters?
Bidi (in the Unicode sense) and bustrophedon (while in a quite different
way "bidirectional") are unrelated and should not be conflated in any way.
The passage in the current proposal authored by Michael and me
contains the passage above cited by Karl, it was included on grounds
of verbal communication of Michael about the preference "by the
committee".
However, I do believe that it should be open for discussion.
Karl suggested (privately) having the punctuation included in the OH
block, alongside with the Bidi_Mirrored=Yes property.
Naa. Bidi_Mirrored is for handling Arabic, Hebrew and similar scripts.
It's NOT for handling bustrophedon, which mirrors *all* glyphs (once)
on every second line. Bidi override controls never mirror characters
which have Bidi_Mirrored=FALSE. Also the bidi overrides do not go well
together with bustrophedon and automatic line breaking. Bustrophedon
is simply a quite different beast from Arabic/Hebrew/etc. Bustrophedon
should simply graphically mirror the entier line, every second line.
