Some commands and environments recognised
A list of some accepted LaTeX commands and environments follows, differences to the usual interpretation being given
- diacritics: Portuguese accents and cedilla
- styles not in math mode:
\em,\bf,\tt,\it,\sf,\textem,\textbf,\texttt,\textit,\textsf,\underline
In (Portuguese) Braille there are only two: normal and emphasised, so that a style command makes a change from one to the other. This means that an even number of these commands in sequence has no effect at all - mathematical environments:
$,$$,\[ \],equation,eqnarray,eqnarray*
They are all dealt with in the same way and any box (like\mbox) may only have a sequence of letters that may be surrounded by blanks which are ignored. The sequence$.$is translated to period - sectioning and footonotes:
\section,\section*,\subsection,\subsection*,\subsubsection,\subsubsection*,\paragraph,\subparagraph,\chapter,\chapter*,\part,\part*,\footnote
The text of the argument is translated without any special indication. There is no numbering and optional arguments are discarded - boxes:
\mbox,\fbox,\makebox,\framebox,\parbox
The box content is translated without any special indication. All other arguments are ignored. A box in a mathematical environment can only have a sequence of letters, may be with surrounding blanks that are discarded.
