 \label{ssection-cv}
 
-\FOTF{} provides eleven ``Character Variants’’ options to choose between
-different glyphs for Greek characters and some others, see table~\vref{cv}
-for the full list.
-
-For instance, to get \cmd{epsilon} and \cmd{phi} typeset as $\varepsilon$
-and $\varphi$ instead of $\epsilon$ and $\phi$, you can add option
-\verb+CharacterVariant={3,6}+ to the \cmd{setmathfont} call:

-\setmathfont{Erewhon Math}[CharacterVariant={3,6}]

-This  works for all shapes and weights of these characters:
-\verb+$\symit{\epsilon}$+,\\
-\verb+$\symup{\epsilon}$+, \verb+$\symbf{\epsilon}$+,
-\verb+$\symbfit{\epsilon}$+ are output as
-\setmathfont{Erewhon Math}[CharacterVariant={3,6}]

-instead of
-\setmathfont{Erewhon Math}
-$\symit{\epsilon}, \symup{\epsilon}, \symbf{\epsilon}, \symbfit{\epsilon}$.
-
-The same is true for \verb+\phi+ of course. Please note that curly braces are
-mandatory whenever more than one ``Character Variant’’ is selected.
+\FOTF{} provides fourteen ``Character Variants’’ options, listed on
+table~\vref{cv}, to choose between different glyphs for Greek characters
