The following functions implement the association between a joining group and its name.

Function: const char * uc_joining_group_name (int joining_group) ¶

Returns the name of a joining group.

Function: int uc_joining_group_byname (const char *joining_group_name) ¶

Returns the joining group given by name, e.g. "Teh_Marbuta". This lookup ignores spaces, underscores, or hyphens as word separators and is case-insignificant.

The following function gives the joining group of every Unicode character.

Function: int uc_joining_group (ucs4_t uc) ¶

Returns the joining group of a Unicode character.
