+fonts with versions of TeX that are limited to TFM files, Type 1 PostScript
+fonts, and 8-bit font encodings.
+
+Some glyphs that are traditionally available in TeX math fonts are not yet
+available in the STIX Two OpenType fonts.  In such cases, we have chosen to
+omit them from the @code{stix2} package rather than create incompatibilities
+between the OpenType and Type 1 versions.")
