The following function views general categories as sets of Unicode characters.

Function: bool uc_is_general_category_withtable (ucs4_t uc, uint32_t bitmask) ¶

Tests whether a Unicode character belongs to a given category. The bitmask argument can be a predefined general category bitmask or the combination of several predefined general category bitmasks.

This function uses a big table comprising all general categories.
