Add Support for TI's Characters in Default Font

[merthsoft]

I wanted to draw the left/right solid arrows that TI has in their font. I did the following:

gfx_SetTextXY(0, 0);
gfx_PrintChar((char)195);

And it printed garbage. Mateo says "graphx just defines the ascii characters \ so 7bits of char".

It would be really cool to be able to access the full range of TI's font in the default font and support it for other fonts too.

"Other fonts"? What do you mean?

[merthsoft]

I have not yet looked into how fonts work, so just assumed they'd be the same. If they're not--disregard!

theoretically this is now possible with fontlibc - so closing the issue for now :)
