This howto aimed at bloggers wanting to post in more than one language and need bidirectional support. I could not find this info gathered elsewhere, so I’m summarizing what I know here. Distribution license and other info is at the end.
The options I’ve encountered so far:
1. Open two blogs and “ignore” the problem, like Dr. Gadi Taub and others. There are localized RTL themes ans editions of Wordpress in Hebrew ( T1 T2), Arabic ( T1 T2) and Farsi ( T). The maintainer for the Arabic WP is an Israeli, btw.
