Title:
  Multibyte comments broken

Status in Mahara:
  Fix Committed
Status in Mahara 19.04 series:
  Fix Committed
Status in Mahara 19.10 series:
  Fix Committed

Bug description:
  When we post English and Japanese comments on a page "Add comment"
  field, only Japanese characters are corrupted as the attached
  screenshot (mahara_comment.png).

  We can fix the issue using mb_convert_encoding function as below.
  Hopefully this fix helps Mahara multibyte character users.
