class: unicodefuncst

[16:7] extends: object

Data type containing a set of virtual methods used for accessing various Unicode character properties. HarfBuzz provides a default function for each of the methods in #hb_unicode_funcs_t. Client programs can implement their own replacements for the individual Unicode functions, as needed, and replace the default by calling the setter for a method.
