Quoting UAX#27, Unicode 3.1, Section 7.10:
Directionality. Most early Etruscan texts have right-to-left directionality. From the third century BCE, left-to-right texts appear, showing the influence of Latin. Oscan, Umbrian, and Faliscan also generally have right-to-left directionality. Boustrophedon appears rarely, and not especially early (for instance, the Forum inscription dates to 550-500 BCE). Despite this, for reasons of implementation simplicity, many scholars prefer left-to-right presentation of texts, as this is also their practice when transcribing the texts into Latin script. Accordingly, the Old Italic script has a default directionality of strong left-to-right in this standard. When directional overrides are used to produce right-to-left presentation, the glyphs in fonts must be mirrored from the glyphs shown in the tables below. Doesn't that mean that we need to have Bidi Mirroring property as 'Y' for those characters? roozbeh
