    I believe this is a common misunderstanding. For these cases we do not
    require Unicode bidi support, it is only needed to cope with mixed
    directionality, as is common in modern Hebrew and Arabic.

    Just laying out the text from right to left or from top to bottom is not
    a plain text issue, although you could use the Unicode LRO/RLO formatting

    In HTML, you could use <bdo dir=xyz> to force a piece of text to be layed
    out right to left or left to right irrespective of the properties of the
    characters involved. There is no technical or other reason not to add
    boustrophedon, if anyone would wish to finance it or to do it for free
    for Mozilla.
