Reordering of bidirectional text into the @dfn{visual} order happens
at display time. As result, character positions no longer increase
monotonically with their positions on display. Emacs implements the
Unicode Bidirectional Algorithm described in the Unicode Standard
Annex #9, for reordering of bidirectional text for display.
Unicode Bidirectional Algorithm (UBA) described in the Unicode
Standard Annex #9, for reordering of bidirectional text for display.
It deviates from the UBA only in how continuation lines are displayed
when text direction is opposite to the base paragraph direction,
e.g. when a long line of English text appears in a right-to-left
