Thank you very much for this, Idris. What with the other bugs and problems I’ve faced with R2L (in footnotes, etc.), I was starting to wonder whether a more explicit, rather than global, use of RTL might be a better approach. I’m going to experiment with them, at least to learn how to use them with greater focus.
The good news is that apparently Hans has already patched the page-lin.lua file that Wolfgang had identified as the culprit, and it will be included in the next beta.
Many thanks to you, Pablo, Wolfgang, and of course Hans so much for your help in getting these right-to-left issues solved. There are a couple of small bidi issues remaining, including that mentioned in the “footnotes when using RtL (Arabic)” thread. The one or two other ones I will post shortly. But, in any case, I have now completely moved my project over into ConTeXt, confident that it (and the team behind it) can handle all of the needs of a multilingual academic monograph and of a bi-direction, Arabic critical edition’s need
With many thanks,

> PS Unless there is a lot of Latin in the critical edition file, I would probably depend more on explicit dir commands (\righttolet, \lefttoright) and less on bidi, which is still buggy in a number of ways. Beyond the ConTeXt implementation: The unicode bidi algorithm was not designed with advanced typesetting and typography in mind, works best for text-editing etc. per se. so local bidi *may perhaps* be more useful than global bidi for the critical-edition portion your project.
