-\begin_layout Section*
-Minimal failing example for Math.lyx
-\end_layout
-
-\begin_layout Standard
-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
-Computer Modern
-\emph default
- 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
-
-\begin_layout Enumerate
-Changing the math font does not work for Math.lyx:
-\end_layout
-
-\begin_deeper
-\begin_layout Itemize
-Some of the documented packages and examples only work with the default
- math font (no 
-\backslash
-maltese in 
-\begin_inset Quotes eld
-\end_inset
-
-txmath
-\begin_inset Quotes erd
-\end_inset
-
-, package incompatibilities with unicode-math, ...).
-\end_layout
-
-\begin_layout Itemize
-Besides: support for most math fonts is of inferiour quality (missing optical
- sizes for indices, limited set of symbols)
-\end_layout
-
-\end_deeper
-\begin_layout Subsection*
-Missing characters with Latin Modern
-\end_layout
-
-\begin_layout Standard
-Excerpts from Math.lyx that lead to 
-\begin_inset Quotes eld
-\end_inset
-
-missing character
-\begin_inset Quotes erd
-\end_inset
-
- errors and discussion of reasons and possible workarounds:
-\end_layout
-
-\begin_layout Quote
-Bold Formulas
-\end_layout
-
-\begin_layout Quote
-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:
-\begin_inset Formula 
-\[
-\mathbf{\int_{n}^{2}f(\theta)=\Gamma}\qquad\textrm{equation with \textbackslash mathbf}
-\]
-
-\end_inset
-
-
-\end_layout
-
-\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
-Accents in Text
-\end_layout
-
-\begin_layout Quote
-With the following commands all letters can be accented.
- The commands must be inserted in \SpecialChar TeX
- mode.
