int unicode_derived_xid_start_lookup(char32_t c);

DESCRIPTION

These functions look up the character's various derived core properties. unicode_derived_incb_lookup() returns one of the UNICODE_DERIVED_INCB_value from courier-unicode.h, all others return a non-0 value if the character has the derived property.
