er, the characters in "name" don't seem to match the characters in the
query - '국방비' vs. '북한의' - does that have any bearing?

FWIW (on 7.4.3):

test=#  select * from t1 ;
 id | value
----+--------
  1 | 日本
  2 | 日本語
  3 | 北海道
(3 rows)

test=#  select * from t1 where value ~ '日';
 id | value
----+--------
  1 | 日本
  2 | 日本語
(2 rows)

test=# select * from t1 where value like '日%';
 id | value
----+--------
  1 | 日本
  2 | 日本語

test=# select * from t1 where value like '北海%';
 id | value
----+--------
  3 | 北海道
(1 row)
