Flow direction of mathematical formula for ar* locales
|Reported by:||tomerm@…||Owned by:||emmons|
Direction of math formula in Arabic speaking countries may be different from what English speaking countries are accustomed to.
In some countries it can be LTR (just like in USA):
x + y = z
While in others it can be RTL:
z = y + x
Some initial information on preferences in different countries is available from: http://www.wiris.com/editor/docs/resources/arabic-numbers-countries
Similarly to NumberingSystem property (which is different in different Arabic speaking countries: "arab" vs "latn"), the suggestion is to define MathFormulaDir property with possible values "ltr" and "rtl". For overwhelming majority of locales it will have "ltr" value. For several Arabic locales it will have "rtl" value.
