Generate visual Braille

[raphael.poitevin@gmail.com (Raphaël POITEVIN)]

Hello,

I'm looking for a solution to generate a PDF with Braille, which could
be 3D printed, deep embossed or swell embosed.

I tested several solutions which have their advantages and their
inconvenients. Those solutions are based on a TrueType police:
https://www.rnib.org.uk/braille-and-other-tactile-codes-portal-writing-and-producing-braille/braille-fonts

The main problem is those fonts are based on american table, which get
difficult to write french for instance. We have to type special
characters for capital sign, aaccents, digit etc.

1. XeLaTeX, UTF-8 input:

Writing french is very hard, especialy for some characters which are
reserved characters in LaTeX. For instance, 8 digit is \textbackslash.

2. XeLaTeX, unicode input:

Easier but lots of overfull hbox after compilation and truncated lines.

3. Libreoffice, UTF-8 input:

OK, but export PDF seems to insert some spaces before some punctuations.

4. Libreoffice, unicode input:

OK, but no word wrapping at the end of lines.

Any other possibility?

Thanks for helping.

Regards,
