ISSUE:       6798
TITLE:       Add built-in functions UNICODE_CHAR and UNICODE_VAL to convert between Unicode code point and character
DESCRIPTION:
  NB. Only basic checks are peformed here.
  This test mostly will be re-implemented later in order to check more complex cases.
  Lists of unicode characters and their codes:
