I thought that the CSS property setting of
unicode-bidi="normal" had the effect of saying that the normal
Unicode bidi rules were applied to text, and that the direction property
text was effectively ignored (or treated as if it were what is being
suggested as "auto").
To force a text direction in CSS, you must set direction and set the
unicode-bidi property to "embed" or

The key issue is when users are

not uncommon for those users to make use of LTR websites (like
google.com), and enter in RTL text, say
to search for. If the text entry box is in the "wrong"
direction for the text, it is very hard to read and edit. By having an
"auto" option that uses the Unicode BIDI algorithm's default
for setting the text direction (keying off the first strong direction
character of each paragraph), it makes it much easier for users to read
and edit the text that they are typing in.

- Mark, Simon,
- Could you put a few more words around this, explaining why it is
needed and how you think it could be addressed? Then we can discuss
the proposal in the i18n core WG and, if agreed, forward to CSS and any
other WGs for consideration.
- PS: Note that w3c-i18n-ig@w3 is no longer in use. If you are in
the Core WG, you can use public-i18n-core@w3.

I proposed some time ago adding a value "auto" to the css
property to achieve this result.
