Right, doesn't fit in hyphenation. Maybe move this to
https://kba.github.io/hocr-spec/1.2/#font-lang, replace "with tags" with "dir= attribute" and reference https://kba.github.io/hocr-spec/1.2/#valdef-ocr-capabilities-ocrp_dir?

You could also combine some of these sections under one new section, i.e.
HTML entities and Unicode
- Non-breaking spaces must be represented using the HTML
entity. - Different space widths should be indicated using HTML and
 , , ,‌,‍. - Soft hyphens must be represented using the HTML
­entity. - The HTML
‎and‏entities (indicating writing direction) must not be used; all writing direction changes must be indicated with tags. - Furigana and similar constructs must be represented using their correct Unicode encoding.

I think these aspects are worth their own section. e.g. for Whitespace: explain whether repeated whitespace is meaningful, if non-tabular aligned text should use tabs. For hyphenation, whether that's the only encoding (e.g. altoxml/schema#41).

Hyphens are also mentioned in http://kba.github.io/hocr-spec/1.2/#hardbreak
Besides ruby also other special entities are mentioned in the article:
For example, HTML and CSS provide
support for representing fonts, styles, hyphenation,
flexible spacing, justification, kashida (flexible Arabic
characters), Urdu ligatures, Japanese ruby, mixed hor-
izontal/vertical layout, inline changes in writing direc-
tion, and many others.
However, I am also fine with more subsections.

I've moved the paragraph there before and probably will again once I get to the fonts/language section :)

These links are not working and I am not sure there is anything we can link to...

Properly link to dir= and lang= attributes

I just find the HTML5 standard way better. I know we have
in there, but we should rather change that than link to an old spec with bad examples: H<sub>2</sub>O
E = mc<sup>2</sup>
<SPAN lang="fr">M<sup>lle</sup> Dupont</SPAN>The first two should not use sub/sup at all. None of the tags should be upper-case. |
