+hyphenation patterns in UTF-8 format, whereas older systems require
+hyphenation patterns in the 8-bit encoding of the font in use (such encodings
+are codified in the LaTeX scheme with names like OT1, T2A, TS1, OML, LY1,
+etc).  The present package offers a collection of conversions of existing
+patterns to UTF-8 format, together with converters for use with 8-bit fonts in
+older systems.  Since hyphenation patterns for Knuthian-style TeX systems are
+only read at iniTeX time, it is hoped that the UTF-8 patterns, with their
+converters, will completely supplant the older patterns.")
