+together with a large number of support files.  The @code{utf8x.def}
+definition file for use with @code{inputenc} covers a wider range of Unicode
+characters than does @code{utf8.def} in the LaTeX distribution.  The package
+provides facilities for efficient use of its large sets of Unicode characters.
+Glyph production may be controlled by various options, which permits use of
+non-ASCII characters when coding mathematical formulae.  Note that the bundle
+previously had an alias “unicode”; that alias has now been withdrawn, and no
+package of that name now exists.")
