You are right. I have found a free font and it converts the braille characters to normal characters. But as you mentioned that fonts are not standard for different geographical regions/natives. So, the only way I can do it right is to process the braille character via image processing. Like consider the braille chracter as an image and apply the algorithm to identify the pattern and then map it to some dictionary value..
Sample pdf file:http://dl.dropbox.com/u/18670740/BRAILLE%20CODES%20WITH%20TRANSLATION.pdf On a same note with separate question, can we read character from a pdf and store it as image. e.g. if I read 'A' from a PDF file than it should be stored as an Image ??? I want to apply image processing on a braille character (e.g. http://www.alsglobal.net/images/braille.jpg) Thanks.
