Happy 2019 Sudoku

For the new year, we make a puzzle out of the symbols in 'HAPPY 2019'.  Note that unlike the last two holiday puzzles, this one has both letters and numbers.  Finding out which cells contain which is part of the puzzle.  Here we place clues exactly when cells both contain letters or both contain numbers and when the distance between them is seven, eight or nine.
