This error might appear when the MySQL database is encoded as UTF8. In that case, Unicode characters represented with 4 bytes are not accepted. The accepted reply to the following StackOverflow question explains that the database needs to be encoded using the utf8mb4 encoding and the utf8mb4_unicode_ci collation:

A more complete explanation about the utf8mb4 encoding on MySQL can be found here:

In case you need to re-encode your existing Drupal database, there is an experimental Drush command for it at UTF8MB4 Convert.
