MariaDB Addon stops recording after a few hours

Hi,
I want to use the MariaDB Addon. But after setup its works for a few hours and then stops workring.

See this in log:

2019-05-13 03:51:20 ERROR (Recorder) [homeassistant.components.recorder.util] Error executing query: 'latin-1' codec can't encode character '\u2013' in position 11: ordinal not in range(256)

Config:

recorder:
  purge_keep_days: 7
  exclude:
    domains:
      - sun
      - zwave
    entities:
      - sun.sun
      - sensor.time
      - sensor.since_last_boot
  db_url: mysql://hass:xxxx@core-mariadb/homeassistant

no ideas??

Using IOS app by chance? Did this just start for you?

Have a look here. there is a suggestion for a fix.
