## Notes
- You can have any amount of leading and trailing whitespace on all directions, as long as all non-whitespace characters are properly aligned to make the diamond shape.
- A multiline string, character matrix, list of strings, list of lists of characters, and equivalent are acceptable outputs.
- Shortest answer per language, scored in bytes, wins!
