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.

the values used in the array that indicates emphasis and, on the first pass
LibLouis makes through the text, set the array for capital emphasis at that
time. Then handle it along with all other forms of emphasis.

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.

LibLouis, work on and test it while keeping in sync with the master LibLouis

master repository if that is desirable.
