This character coverage ensures +that any character from this common subset that occurs within a math +equation will be correctly displayed, even if it is not a math symbol +with a generally recognised meaning. However, use of the STIX Two +Math font to typeset non-mathematical text is discouraged, and the +Text font family should be used for this purpose. + +\fi + +\subsubsection*{Legend} + +\begin{itemize} + +\item Characters shown in black (e.g., U+0021) are supported directly by +the font. + +\item Characters shown in \textcolor{red}{red} (e.g., U+01CE) are not + directly supported but can be synthesized by a Unicode-aware shaping + engine. (These charts were generated + with \XeTeX\ \number\XeTeXversion\XeTeXrevision.) + +% \textbf{Note}: Many of the characters in this category are poorly +% rendered because of deficiencies in the font's \textsc{gpos} table. +% Plans are being made to address these problems. + +\ifshowghosts +\item Characters shown in \textcolor{gray}{gray} are not supported by + STIX, but are borrowed from Cambria for demonstration purposes. +\fi + +\item Grey squares (e.g., U+0380) indicate code points that are not + assigned a meaning in Unicode 13.0. + +\item Otherwise blank squares that contain a code point (e.g., U+0020) +indicate characters with no visible representation. These may or may +not be zero-width characters; see the Unicode Standard for details. + +\item Completely blank squares (e.g., U+0181) indicate code points + correspondinng to characters that STIX 2.10 does not support. + +\item Black squares (e.g., U+FFFE) indicate noncharacter code points. + +\end{itemize} + +\subsubsection*{Notes} + +\begin{itemize} + +\item Not every composite character supported by the STIX fonts is + included in these charts; only characters that are assigned a code + point by Unicode~13.0 are shown. For example, you will not find + ``x̣'' in these charts since Unicode does not assign a code point to + that character. It can, however, be composed from the sequence U+0078 + LATIN SMALL LETTER X followed by U+0323 COMBINING DOT BELOW. + +% \item Similarly, not every variant glyph of every character is displayed. +% See the STIX 2.10 release notes and accompanying documentation for +% more information on the OpenType font features and stylistic sets +% supported by STIX Two. + +\item Glyphs are shown at size 20\,pt unless otherwise indicated. + +\end{itemize} + +\endinput -- cgit v1.2.3
