Compiling \SpecialChar LyX

's detailed Math manual fails with non-TeX fonts due to missing
|
|
characters.
|
|
The documents uses the default set for LyX documentation:
|
|
\emph on
|
|
Latin Modern
|
|
\emph default
|
|
as text and
|
|
\emph on
|
|

|
for maths.

\end_layout

\begin_layout Standard
|
|
There is no easy solution because of the nature of the Maths documentation:
|
|
|
|
\end_layout
|
|
|
|
\begin_layout Enumerate
|
|
Changing only the text font results in a bad font mix — LyX documentation
|
|
must not give a bad example/showcase.

\end_layout
|

Changing the math font does not work for Math.lyx:

To make a complete formula bold, the command
|
|
\series bold
|
|

|
\backslash

mathbf

|
|

|
|
small Greek letters.
|
|
Furthermore it prints Latin letters always upright, like in the following
|
|
equation:
|
|
\begin_inset Formula

\[

\mathbf{\int_{n}^{2}f(\theta)=\Gamma}\qquad\textrm{equation with \textbackslash mathbf}

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
