Re: [tex4ht] [bug #339] remove/rewrite braille code

Karl - i don't believe we have braille lit sources in svn repo.

It is interesting to know, what kind of system/code/workflow Antonis refers to 
as
"Braille support in tex4ht"

 "SuBrl: A LaTeX to braille converter"
http://www.dotlessbraille.org/gurari.htm
Does anybody know about source files?

Antonis Tsolomitis tells me that the Braille support in tex4ht depends on
liblouis to convert tex4ht's XML output to Braille. and liblouis does not work
with our xml, and won't (they said their target is Office). Ditto for
LaTeXML's XML output.

Therefore it seems we should remove or completely rewrite our Braille stuff,
instead of having code that does nothing useful.

Antonis and others have written latex2nemeth
(http://ctan.org/pkg/latex2nemeth) as another tex parser that outputs braille
directly, since they had a blind student they needed to support right away.

[tex4ht] [bug #339] remove/rewrite braille code

Follow-up Comment #1, bug #339 (project tex4ht):

I didn't even knew there is a braille support in tex4ht :) I know that it
supports EmacsSpeak and JSpeech, I am not sure how relevant these are these
days and I doubt that this support is complete. 

I've done some Liblouis testing really long time ago:
http://tex.stackexchange.com/a/32685/2891
and it seemed that it works on my sample document, I am sure one would face
many issues with real world documents. But what kind of document it expects
other than unicode xhtml with mathml? I have impression that it should be
supported, from my reading of the manual. What might be missing in usual
tex4ht output are xml:lang attributes, it shouldn't be hard to add them with
some configurations for babel. Again, I am not sure if Liblouis even support
that :)
