A simpler definition of the Bidi Algorithm

2010-09-10 Thread Michael D. Adams
Rules W2 through W7 for the Bidi Algorithm [http://www.unicode.org/reports/tr9/] are rather confusing to read. They are not confusing as to what to do but as to why they are done and how to efficiently implement them. After many hours puzzling over them I think I've found a simpler way to define t

The first discussions that lead to the current formulation of the bidi algorithm easily go back 20 years by now. There's some value in not re-stating a specification - even if a new formulation could be found to be 100% equivalent. That value lies in the fact that any reader can tell, by simpl
