After having a glimpse on ECMA-48(Control Functions for Coded Character Sets) I am not sure how this concept would interact with the bidi algorithm - especially if glyphs should be mirrored, rotated or simply reordered.

Reading the font data and processing it into a display representation poses the same resource costs for mirrored, rotated and normal glyphs. The limitations are mainly processing speed and memory/storage. On the display side there are few potential problems. Thomas Kuehne
vertical direction control
Is somebody already using a PUA assignment for vertical text direction controls? from http://www.unicode.org/faq/bidi.html#1 [...] the choice of vertical layout is usually treated as a formatting style; therefore, the Unicode Standard does not define default rendering behavior for vertical text nor provide directionality controls designed to override such behavior. Thanks in advance for any hints, Thomas Kuehne

Markup languages have had vertical layout controls forever. 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. 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. Thomas Kuehne
