Updated article: What you need to know about the bidi algorithm and inline markup

This article was revised substantially.

Translators should consider retranslating the whole article.

This article was revised to provide more clarity. More examples were added, and a new approach was taken, using images for examples and providing links to live code.

The term ‘directional context’ was replaced with ‘base direction’, the meaning and impact of that was expressed better. It also shows a little more clearly the types of problem the bidi algorithm needs help with, and how the proposed solutions related to each other.
