EMPTY_CELLconstant

A GRID OF NUMBERS AS A STRING: for an address, a POST body, and a kept run.

Row-major, one character per cell: a digit for a value, . for an empty cell. Past nine the values are letters, A for 10 up to G for 16 as a 16×16 Sudoku is printed, and on to P for 25 on a 25×25 (symbolOf), so one character is still one cell. Upper case only in a code, so one grid has one spelling. These are the spellings itsutsu.com has always stored, and they decode here unchanged.
