I tried saving a node with a title containing accented characters, and there was an error:
SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect string value: '\xC3\xA1m' for column `db`.`value_revisions`.`value_hash` at row 1: INSERT INTO "value_revisions" ("entity_type", "entity_id", "field_name", "delta", "source_revision_id", "value_hash") VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5); Array ( [:db_insert_placeholder_0] => node [:db_insert_placeholder_1] => 35168 [:db_insert_placeholder_2] => title [:db_insert_placeholder_3] => 0 [:db_insert_placeholder_4] => 35168 [:db_insert_placeholder_5] => Adám ) (/var/www/html/web/core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php:817)
Update the schema to allow non-ascii characters, using varchar instead.
See above...

I tested the fix and am now able to see that I can save non-ascii characters into the value_hash column
