  39  * @short_description: Unicode character property access
  40  * @include: hb.h
  41  *
  42  * Unicode functions are used to access Unicode character properties.
  43  * With these functions, client programs can query various properties from
  44  * the Unicode Character Database for any code point, such as General
  45  * Category (gc), Script (sc), Canonical Combining Class (ccc), etc.
  46  *
  47  * Client programs can optionally pass in their own Unicode functions
  48  * that implement the same queries. The set of functions available is
  49  * defined by the virtual methods in #hb_unicode_funcs_t.
  50  *
  51  * HarfBuzz provides built-in default functions for each method in
  52  * #hb_unicode_funcs_t.
