Hello Aqil.


Since I am part of the team developing and maintaining the math capabilities in DBT, I imagine you would prefer  hearing from someone else. I do not have the information to compare the tools in DBT for LaTeX to Nemeth conversion with any other tools. But I will try to answer your first question.


I think that in general DBT does a good job of converting LaTeX to Nemeth Code. Over the years we have done our best to be responsive to problem reports that have come to us.


For LaTeX formatting, DBT's LaTeX importer does its best to convert the important formatting commands to the equivalent braille format and to filter out the rest.


Here are a few examples of recent changes in DBT's LaTeX importer and in support for Nemeth Code.


We have adapted DBT's LaTeX importer for creating Nemeth Code in UEB 
context, using the UEB start and end Nemeth indicators where needed but 
not using them in other places.


We have made it much more straightforward to get Nemeth Code for 
technical notation in non-English documents.


In DBT 12.4, the most recent DBT version, we have added initial support 
for several braille math codes from around the world that are new to 
DBT. To go along with that, we added support for LaTeX in UTF8 documents 
containing characters outside of ASCII. This makes it possible to import 
LaTeX files containing European languages with accented letters, Russian 
text, Arabic text and so on. As a side effect, this fixed some other 
issues. For example, it fixed a problem that a user found when his 
hand-coded English document used an em-dash instead of a hyphen.


LaTeX importing is also part of the fairly new DBT for Mac.


This all helps to make the DBT LaTeX importer more flexible.


Please feel free to contact Duxbury with specific questions about our 
LaTeX importing and support for Nemeth Code.


Best regards,

Caryn
