LaTeX rendering makes "-2" illegal

[eshmoylova]

In Section 3.2 there is a non-normative section under the table that makes it look like "-2" is illegal in Modelica:

Looking at the source, it looks like there might be some escape characters needed. It is written as -- which LaTeX renders as an en-dash.

ModelicaSpecification/chapters/operatorsandexpressions.tex

Lines 99 to 101 in 57e159f

	--2 // = 2 in Mathematica/MATLAB; is illegal in Modelica
	++2 // = 2 in Mathematica/MATLAB; is illegal in Modelica
	2--2 // = 4 in Mathematica/MATLAB; is illegal in Modelica

Also in the caption of the table the the array construction operator appears as \{ \}

ModelicaSpecification/chapters/operatorsandexpressions.tex

Line 44 in 57e159f

\caption{Operators in order of precedence from highest to lowest, as derived from the Modelica grammar in \cref{modelica-concrete-syntax}. All operators are binary except the postfix operators and those shown as unary together with \emph{expr}, the conditional operator, the array construction operator \lstinline!\{ \}! and concatenation operator \lstinline![ ]!, and the array range constructor which is either binary or ternary. Operators with the same precedence occur at the same table row.}\label{tab:operator-precedence}

Both -- and {} appear correctly in the pdf.

The second issue is reported as brucemiller/LaTeXML#1377 so it seems we can just wait until it is fixed in LaTeXML; as I don't see any obvious good work-around.

[sjoelund]

Well, a space between them doesn't hurt that much, right? Otherwise, a zero-width space might work?

[HansOlsson]

Yes, I was planning that as a PR for the first issue, was just testing it first.

Now that the fix changed in the last minute from plain space to $\hspace{0pt}$, it turned from a nice example into a some sort of hacky workaround. As such, there should be a comment with a link to the relevant LaTeXML issue so that we can track when it get's fixed and the workaround can be removed.
