| typedef struct hb_unicode_funcs_t hb_unicode_funcs_t |
hb_unicode_funcs_t:
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.
