A question was raised during the F2F meeting in NYC, about the proper internationalization of UTF-8 metadata values (eg. the book title).

I quote Ivan from the minutes: "On the i18n side, we will need to be careful about ids, uris, iris, etc. w/respect to i18n char-sets. Another area we need to be careful about is metadata, which also have issues with the char-sets for the actual text content. One example is mixing bidi text in the metadata content.",

Reading http://www.iamcal.com/understanding-bidirectional-text/, I see here a use of the HTML dir attribute, which will not be available natively in a JSON manifest; so we may have to create a JSON dir attribute representing document order. I also see the "implicit marker characters" (Left-to-Right Mark and Right-to-Left Mark) which help tailoring the direction of "neutral" characters. And the existence of "explicit markers" which describe a local text direction.

Therefore it appears that the only item we need to add to a JSON manifest to assure proper rendering of international text is a "document order" (a dir attribute that can be injected in the HTML rendering of the metadata values).

Any thought on this before I create a Github issue on the subject?
