Minimal failing example for Math.lyx
\end_layout
\begin_layout Standard
\SpecialChar LyX
's detailed Math manual fails with
\begin_inset Quotes eld
\end_inset
missing character
\begin_inset Quotes erd
\end_inset
errors for the following reasons:
\end_layout
\begin_layout Quote
Fractions
\end_layout
\begin_deeper
\begin_layout Standard
For nested fractions the command
\series bold
\backslash
cfrac
\series default
can be used.
Here is an example:
\end_layout
\begin_layout Standard
\begin_inset Formula
\begin{align*}
\textrm{created with \textbf{\textbackslash frac}} & & \textrm{created with \textbf{\textbackslash cfrac}}\\
\frac{A}{B+\frac{C+\frac{E}{F}}{D}} & & \cfrac{A}{B+\cfrac{C+\cfrac{E}{F}}{D}}
\end{align*}
\end_inset
\end_layout
\end_deeper
\begin_layout Standard
In
\begin_inset Quotes eld
\end_inset
mathematical text
\begin_inset Quotes erd
\end_inset
and with tex2lyx, the
\backslash
textbackslash became 0x29f5 REVERSE SOLIDUS OPERATOR.
After adding
\begin_inset Quotes eld
\end_inset
deprecated
\begin_inset Quotes erd
\end_inset
in lib/unicodesymbols, this is fixed.
\end_layout
\begin_layout Standard
The converted characters should be replaced with
\begin_inset Quotes eld
\end_inset
\backslash
textbackslash
\begin_inset Quotes eld
\end_inset
.
\end_layout
\begin_layout Quote
Bold Formulas
\end_layout
\begin_deeper
\begin_layout Standard
To make a complete formula bold, the command
\series bold
\backslash
mathbf
\series default
from the previous subsection cannot be used, because it doesn't work for
small Greek letters.
Furthermore it prints Latin letters always upright, like in the following
equation:
\end_layout
\begin_layout Standard
\begin_inset Formula
\[
\mathbf{\int_{n}^{2}f(\theta)=\Gamma}\qquad\textrm{equation with \textbackslash mathbf}
\]
\end_inset
\end_layout
\end_deeper
\begin_layout Standard
Capital Greek characters in
\backslash
mathbf lead to
\begin_inset Quotes eld
\end_inset
missing character
\begin_inset Quotes erd
\end_inset
errors with non-TeX fonts.
Small Greek characters are not bolded, because TeX treats them as symbols,
not letters (unless you load the package
\emph on
isomath
\emph default
or
\emph on
fixmath
\emph default
).
\end_layout
\begin_layout Quote
Special Characters in Mathematical Text
\end_layout
\begin_deeper
\begin_layout Standard
The following commands can only be used in mathematical text or in \SpecialChar TeX
mode:

Examples for accented characters missing in Latin Modern:

leads to 0x0361 COMBINING DOUBLE INVERTED BREVE (ligature tie) and

\end_layout

Using a different non-tex font is not recommended for the

manual, because TeX-Maths uses Computer Modern which matches with Latin
Modern and looks suboptimal with other fonts.

OTOH, examples for ERT commands to get accented text letters are not really
helpfull in a mathematics documentation even when mathematical text can
be (ab)used to get them.
