The problem arose at very resource limited devices, thus no HTML nor RTF etc.. In fact there is no higher level protocol other than plain strings/text.
I don't think I know of a scenario where it is crtical for a resource limited device to display the kinds of texts you list below.
For CJK, use of horizontal text is common for resource limited devices such as LED or small LCD panel displays, or, for that matter, most computer interfaces (as opposed to formatted documents on a computer).
While crawling through the Pango and SilGraphite rendering engines I noticed that they provide(or are planning to) an interface for vertical text. For CJK, old European in-scripts and especially Egyptian hieroglyphs it would be good to have a common control set - otherwise plain text can't be used for data exchange.
