[BRLTTY] some charactars don't show

[Daniel Dalton]

Hi,

On my braille display, when I read some charactars eg. accented
charactars, I just see a ? mark on my braille display. I think the
terminal displays a null char... So how can I fix this so more
charactars show? And I don't get the null charactars?

Thanks,

Daniel.
