+will be set to the Unicode script of the first character in
+the buffer that has a script other than %HB_SCRIPT_COMMON,
+%HB_SCRIPT_INHERITED, and %HB_SCRIPT_UNKNOWN.
+
+Next, if buffer direction is not set (ie. is %HB_DIRECTION_INVALID),
+it will be set to the natural horizontal direction of the
+buffer script as returned by hb_script_get_horizontal_direction().
+If hb_script_get_horizontal_direction() returns %HB_DIRECTION_INVALID,

+
+Finally, if buffer language is not set (ie. is %HB_LANGUAGE_INVALID),
+it will be set to the process's default language as returned by
+hb_language_get_default().  This may change in the future by
+taking buffer script into consideration when choosing a language.

+
+The format for specifying feature strings follows. All valid CSS
+font-feature-settings values other than 'normal' and the global values are
+also accepted, though not documented below. CSS string escapes are not
+supported.
+
+The range indices refer to the positions between Unicode characters. The
+position before the first character is always 0.
+
+The format is Python-esque.  Here is how it all works:
+
+&lt;informaltable pgwide='1' align='left' frame='none'&gt;
+&lt;tgroup cols='5'&gt;
+&lt;thead&gt;
+&lt;row&gt;&lt;entry&gt;Syntax&lt;/entry&gt;    &lt;entry&gt;Value&lt;/entry&gt; &lt;entry&gt;Start&lt;/entry&gt; &lt;entry&gt;End&lt;/entry&gt;&lt;/row&gt;
+&lt;/thead&gt;
+&lt;tbody&gt;
+&lt;row&gt;&lt;entry&gt;Setting value:&lt;/entry&gt;&lt;/row&gt;
+&lt;row&gt;&lt;entry&gt;kern&lt;/entry&gt;      &lt;entry&gt;1&lt;/entry&gt;     &lt;entry&gt;0&lt;/entry&gt;      &lt;entry&gt;∞&lt;/entry&gt;   &lt;entry&gt;Turn feature on&lt;/entry&gt;&lt;/row&gt;
+&lt;row&gt;&lt;entry&gt;+kern&lt;/entry&gt;     &lt;entry&gt;1&lt;/entry&gt;     &lt;entry&gt;0&lt;/entry&gt;      &lt;entry&gt;∞&lt;/entry&gt;   &lt;entry&gt;Turn feature on&lt;/entry&gt;&lt;/row&gt;
+&lt;row&gt;&lt;entry&gt;-kern&lt;/entry&gt;     &lt;entry&gt;0&lt;/entry&gt;     &lt;entry&gt;0&lt;/entry&gt;      &lt;entry&gt;∞&lt;/entry&gt;   &lt;entry&gt;Turn feature off&lt;/entry&gt;&lt;/row&gt;
