+ * @short_description: Unicode character property access
+ * @include: hb.h
+ *
+ * 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.
+ *
+ * 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 #hb_unicode_funcs_t.
+ *
+ * HarfBuzz provides built-in default functions for each method in
+ * #hb_unicode_funcs_t.
