i try this library,is very cool.
but in NON-ASCII char there is some problem...
because i'm italian, the chars "à" "è" "ì" "ò" "ù" is much in use.
if i put these chars in "DEMO" and in "SCROLLING" i see correct greek character,
if i put these chars in "SMOOTH_SCROLLING" i see a strange char, apparently any in the font.h
if necessary i will edit the font.h with correct ones, but is useless if not work in smooth mode!
can you help me, please?
thanks

Perhaps i'm doing something really silly (incredibly possible) but i cannot send my data to the modules without receiving an error:

exit status 1
no matching function for call to 'MAX7219::sendString(String&)'

i've included the arduino sketch, perhaps you can take a look at it and tell me what i'm doing wrong, and perhaps how i can convert my information into something usable by the library...
