I think you're looking for U+263A. The best way to represent this in source code is with a Unicode escape sequence:

val smiley = "\u263a";

You then need to check that:

  • Your database is able to store it (check the type of your field, potentially collation, potentially database connection settings)
  • You can retrieve it correctly from the database
  • Whatever you want to display it on is able to support it (check the font, aside from anything else)

Given the number of ways in which it can go wrong, it's important to work out exactly where any problems are - which usually involves checking the UTF-16 code unit within the string you're trying to display, rather than just going straight for "does it display properly".
