Unfortunately I do not own a CFA-632 or CFA-634 myself.
So I cannot really test the code.

Did you try with the parameter NewFirmware=0 ?
Did it change the output somehow ?

If you have a CFA-632 with a firmware >= 2.0 (shown in the boot screen of the
LCD), NewFirmware=1 should be O.K in principle.
With lower firmware versions it should be set to 0.

Other users have reported similar problems with some garbled characters.

I guess the problem is in the function CFontz_flush() where I output simple
characters as well as commands to write directly to the LCD in one write
(the for (...) loop from line 360 to 376).
Maybe splitting these commands in to multiple writes (regular charactrs in
a bunch, one special character, ....) can help.

If I am doing the coding this will be a very time consuming task as
I am not able to test it.

So, everybody with a cFA-632 or CFA-634, please have alook at the
CFontz_flush() function in the CFontz.c file !!
