Thank you Joseph. I just want to say that I agree that close dialog between
braille authorities and software developers would be very beneficial to the
future of braille and UEB in particular. That has been on my mind a lot lately.

Hi Christo,
As one of the LibLouis table maintainers for Unified English Braille, I do know
how rewarding it is to introduce UEB to LibLouis users and developers around
the world. However, throughout the course of UEB table development, I and
others here felt that there are certain things in UEB itself that may need to
be modified for programs such as LibLouis to take advantage of it.
Some of my own concerns include smoother transition between literary and math,
certain rules that causes back translation problems and so on. In short, some
of us here felt that UEB's emphasis in heuristic transcription practices (that
is, human transcribers deciding what to do with forward and back translation
issues based on formal rules) may have caused issues when computer programs are
tasked to "transcribe" (forward and back translate) text into UEB. Thus I and
others (especially those of us with programming
background) would like to suggest having a regular dialogue between us and
ICEB/UEB committee in hopes of making UEB friendly towards both humans and
computers.
Thanks, and I hope best of luck to you and ICEB.
Cheers,
Joseph

Hello all
On behalf of the International Council on English Braille (ICEB) I wish to say
that we are extremely pleased about this development. It is essential that
LibLouis must make provision for these aspects of the UEB.
We wish the developer every success with this endeavour.
Kind regards
Christo de Klerk - President: International Council on English Braille

Hi Keith,
This sounds good. I will give whatever help I can.

LibLouis currently has a few shortcomings that need to be addressed before we
can achieve the quality output we need. A couple of these have already been
partially implemented by us or others.

capitalization is handled so that internally LibLouis simply treats it as
another form of emphasis. The only differences being that the attributes used
for the capitalization is inherent in the text and does not need to be passed
in as an argument when translating, and of course LibLouis handles
capitalization in reverse as well as forward translation.

LibLouis makes through the text, set the array for capital emphasis at that
time. Then handle it along with all other forms of emphasis.

current implementation needs to be enhanced so that it not only knows when the
emphasis flags change but exactly how they change. This is in fact the only way
to make capitalization as a form of emphasis work. An additional benefit of
this is of course handling mixed bold, italics, and underlined text even if
they are irregularly mixed.

but we don't see a way to do this for our purposes. We plan to fork LibLouis,
work on and test it while keeping in sync with the master LibLouis code as we
can, and then at some point work on merging our work back to the master
repository if that is desirable.
