I do not disagree with what Peter outlined in general, I do question
where the line between plaintext and rich text should lie.
If it is customary and common, e.g., for a script to be written both
vertically and horizontally, even though vertical text display is
commonly considered to be a formatting or shaping issue, I feel it
should be, for that script, part of its plaintext properties.
If this makes implementation and documentation difficult, so be it.<br clear="none">
