I don't think that matters anyways. Unicode strings are always in "logical"
order, not display order. Displaying the string in the right order is up to
the display engine in the Unicode world-view.
I'm not sure what to think about this though. It may be that Arabic notation
are close enough that it would be straightforward (IIRC decimal notation was
invented in the Arabic world after all). But other writing systems have some
pretty baroque notations which would be far more difficult to convert.
If anything I would expect this kind of conversion to live in the same place
as things like roman numerals or other more flexible formatting.
Ask me about EnterpriseDB's 24x7 Postgres support!
