Re: introduction and question about braille unicode

Hello Peter,

Thanks for the resources! Much appreciated! Will have a look.
The site we are working on uses braille patterns to draw some graph on the
braille display. It isn't a regular graph, but an actual overview of the
graph which we calculate according to some method we have developed. We
need to use those patterns to have full control on the shape of the braille
data we want to draw on the display. Do you have an access to a braille
display so I can send you some sample you can examine if do you think this
is necessary?
Happy to elaborate more on what we are doing if this is not clear enough.

Have a great time!
Mohammad
