I could not replicate with simple case:

select version();
version

------------------------------------------------------------------------------------
PostgreSQL 10.5 on x86_64-pc-linux-gnu, compiled by gcc (SUSE Linux)
4.8.5, 64-bit

CREATE OR REPLACE FUNCTION public.semantic_normalize(title text)
RETURNS text
LANGUAGE sql
AS $function$
SELECT lower(unaccent(btrim(regexp_replace($1,
'\s+', ' ', 'g'), ' "')))
$function$

CREATE TABLE unaccent_test(title text);

INSERT INTO unaccent_test values ('Hukić'), ('Böttcher'), ('ÀÁÂÃÄÅ'),
('électro');

CREATE INDEX ix_semantic_normalize_title on unaccent_test(title);

VACUUM ANALYZE unaccent_test;
VACUUM

vacuumdb -U postgres -z -t unaccent_test test
vacuumdb: vacuuming database "test"

The only thing I can think of is that you have an older version of
vacuumdb that is not aware of the schema specification changes in the
newer versions of Postgrse.
