In the menu bar there is a kind of an input mode selector, where

this region code or whatever the number is that corresponds to each
of the input methods, so that my program can turn text entry right
to left when Hebrew is selected. But none of the simple calls in
the script manager seem to return this number. The keyboard script
typically stays at value 126 (unicode), and I need to distinguish
between hebrew and other input languages. I will probably do a
font switch for the user as well.
This is not my area of expertise, but I think you're going about it
the wrong way:
- The old-style scripts and region codes do not support all languages.
- The approach you're wanting to use requires the application to know
more about languages than it really should.
- I assume Arabic, for example, allows people to type at least some
non-Arabic text, such as Roman digits. You need to chose direction
based on the characters, not the input method.
Each Unicode character has a direction associated with it in the
Unicode standard. If you use that instead of relying on knowledge
about specific languages your application will work with all
languages Mac OS X supports now and in the future. I don't know the
APIs for this stuff, but I know they exist.
You have to use a different mechanism to determine the best font to
use, but again, basing it on a language or script is probably not the
best option. As I said, this is not my area of expertise. However, by
telling us what you really want to accomplish you have the best
chance of getting the best advice.
