I have no opinion on whether HTML is the right format for OCR output.

If we are on the subject, though, OCR from bidi text is devilishly hard. You
have to run a visual-to-logical transformation (which is enough of a
complication by itself). And you would have to guess which of the line breaks
in the original text are actually line wraps, and which are paragraph breaks,
since for the line wraps, you do indeed need line separators. For example,
let's say this is the original visual order in the printed RTL book:

   ali baba and the" SI YROTS EHT FO EMAN EHT
                                 ."40 thieves

The correct logical-order content would be:

THE NAME OF THE STORY IS "ali baba and the[LINE SEPARATOR]
40 thieves".[PARAGRAPH SEPARATOR]

If one used a [PARAGRAPH SEPARATOR] at the end of the first line, it would get
displayed as:

   ali baba and the" SI YROTS EHT FO EMAN EHT
                                 ."thieves 40

I don't have anything. But I know that it will come and bite me on the behind
one day.
