The led_off array used 0xB7 (Latin-1 middle dot) but it heavily depends on
the source code encoding.  Directly using 0xB7 here is very dangerous and
Clang causes a compiler warning ("-Winvalid-source-encoding").
On the other hand, using '\u00b7' here will assume UTF-8.

As a workaround, this commit replaces uses of 0xB7 with '.'
(regular ASCII dot).
