If you’re talking about what happens
in boustrophedon text, versus then I’d treat it as a presentation
issue, not an encoding issue. IMO, it would be a serious problem if you have to
encode an alpha using a distinct character just because it happened to come
(with a given text size and page metrics) on the RTL run of boustrophedon
layout rather than a LTR run. At the *very most*, you might propose control
characters that can be used to distinguish whether characters in a given run of
text should be rotated or mirrored if part of a RTL line, but even there I
would be inclined to leave that to higher-level processing and protocols. If you’re talking about variations among
archaic documents in how particular letters are written, apart from line
direction issues, e.g. versus then you might have a case for proposing
variation-selector sequences. Peter Globalization Infrastructure and Font
