<p>Unicode functions are used to access Unicode character properties.
With these functions, client programs can query various properties from
the Unicode Character Database for any code point, such as General
Category (gc), Script (sc), Canonical Combining Class (ccc), etc.</p>
<p>Client programs can optionally pass in their own Unicode functions
that implement the same queries. The set of functions available is
defined by the virtual methods in <a class="link" href="harfbuzz-hb-unicode.html#hb-unicode-funcs-t" title="hb_unicode_funcs_t"><span class="type">hb_unicode_funcs_t</span></a>.</p>
<p>HarfBuzz provides built-in default functions for each method in
