<p>
Pango supports bidirectional text (like Arabic and Hebrew) automatically.
Some applications however, need some help to correctly handle bidirectional
text.
</p>
<p>
The <a class="link" href="pango-Bidirectional-Text.html#PangoDirection"><span class="type">PangoDirection</span></a> type can be used with <a class="link" href="pango-Text-Processing.html#pango-context-set-base-dir" title="pango_context_set_base_dir ()"><code class="function">pango_context_set_base_dir()</code></a> to
instruct Pango about direction of text, though in most cases Pango detects
that correctly and automatically.  The rest of the facilities in this section
are used internally by Pango already, and are provided to help applications
that need more direct control over bidirectional setting of text.

The <a class="link" href="pango-Bidirectional-Text.html#PangoDirection"><span class="type">PangoDirection</span></a> type represents a direction in the
Unicode bidirectional algorithm; not every value in this

for example, the return value of <a class="link" href="pango-Bidirectional-Text.html#pango-unichar-direction" title="pango_unichar_direction ()"><code class="function">pango_unichar_direction()</code></a>
and <a class="link" href="pango-Bidirectional-Text.html#pango-find-base-dir" title="pango_find_base_dir ()"><code class="function">pango_find_base_dir()</code></a> cannot be <a class="link" href="pango-Bidirectional-Text.html#PANGO-DIRECTION-WEAK-LTR:CAPS"><code class="literal">PANGO_DIRECTION_WEAK_LTR</code></a>
or <a class="link" href="pango-Bidirectional-Text.html#PANGO-DIRECTION-WEAK-RTL:CAPS"><code class="literal">PANGO_DIRECTION_WEAK_RTL</code></a>, since every character is either
neutral or has a strong direction; on the other hand
<a class="link" href="pango-Bidirectional-Text.html#PANGO-DIRECTION-NEUTRAL:CAPS"><code class="literal">PANGO_DIRECTION_NEUTRAL</code></a> doesn't make sense to pass

values come from an earlier interpretation of this
