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.")

     "The EC fonts are European Computer Modern Fonts, supporting the complete
LaTeX T1 encoding defined at the 1990 TUG conference hold at Cork/Ireland.
These fonts are intended to be stable with no changes being made to the tfm
files.  The set also contains a Text Companion Symbol font, called @code{tc},
featuring many useful characters needed in text typesetting, for example
oldstyle digits, currency symbols (including the newly created Euro symbol),
the permille sign, copyright, trade mark and servicemark as well as a copyleft
sign, and many others.  Recent releases of LaTeX2e support the EC fonts.  The
EC fonts supersede the preliminary version released as the DC fonts.  The
fonts are available in (traced) Adobe Type 1 format, as part of the
@code{cm-super} bundle.  The other Computer Modern-style T1-encoded Type 1
set, Latin Modern, is not actually a direct development of the EC set, and
differs from the EC in a number of particulars.")
