The server's driver framework has alternative implementations for vbar,
hbar, cursor, bignum, icon and heartbeat functions, that will be used if
the driver does not implement the function. For the heartbeat this
alternative function is implemented by calling the icon function for the
ICON_HEART_OPEN and ICON_HEART_CLOSED icons you mentioned. The icon
function alternative will place the "#" "-" and "+" characters you also
mentioned. All this is in server/driver.c

Maybe you already knew this, I hope this can be of help.

The heartbeat can also be disabled on global, per client or per screen
level. Then only a ICON_BLOCK_FILLED is drawn.
