Peter Courlis asked
"Is there a S/W application or DTP S/W that is used for
Arabic, Farsi (left to right) languages in popular use, today?"
"Yes, Microsoft Word (Windows only) provides this support.
InDesign ME offers this support (both platforms); maybe future
versions of InDesign might also natively support right-to-left"
I think it used to be the case on the Mac that right to left language
docs were mainly created in Nisus (http://nisus.com/). The OSX
upgrade of Nisus still does it, but you might want to enter "Hebrew"
in the user forums search and read some of the posts. The new kid on
the block is a word processor called Mellel
(http://www.redlers.com/index.html) which looks like it would be well
worth investigating. In fact, it may even be a plausible replacement
for FrameMaker for (English) technical writing on the Mac.
