[BRLTTY] Special char and brlapi

[Tayky]

Hello all,
For my student project, I used the brlapi for create the apps optize in braille.
But I have some problem:
1: When I use the function brlapi_writeText() for display a simple message, ok no problem.
But when I write a special message with special char like "é", "ç", ...
brlapi error, the size of paquet is too large.
Do you have a solution ?

2: I use brlapi_readKey(), But I want to use a macro for call a Key for all device.
exemple:
c: 
if (KEY_LEFT == brlapi_readKey())
printf("ok\n");

Thank in advance
Tayky
