\section{Introduction}

This document describes the \TeX\ text Cyrillic (LCY) encoding. It is
an 8-bit extension of the OT1 encoding, so the first 128 slots fully
coincide with OT1, and this part of file was taken from `ot1.etx' by
Alan Jeffrey and Ulrik Vieth. This font encoding is not standard (as
follows from it's name), but is important e.g.\ for Plain TeX-based
macro packages for Cyrillic typesetting. This encoding is close to the
so-called `New Alternative Variant' of the Microsoft MS-DOS cp866
Cyrillic encoding, and supports at least Russian, Ukrainian and
Byelorussian glyph repertory.

To use this encoding, you should define the following macros:
\begin{itemize}
\item \verb|\lc{A}{a}| should return the name of a lower-case
   glyph, for example `{\tt a}' or `{\tt Asmall}'.

\item \verb|\uc{A}{a}| should return the name of an upper-case
   glyph, for example `{\tt A}' or `{\tt Amedium}'.

\item \verb|\lclig{FI}{fi}| should return the name of a lower-case
   ligature, for example `{\tt fi}' or `{\tt FIsmall}'.

\item \verb|\uclig{FI}{fi}| should return the name of an upper-case
   ligature, for example `{\tt FI}' or `{\tt FImedium}'.

\item \verb|\digit{zero}| should return the name of a digit, for
   example `{\tt zero}' or `{\tt zerooldstyle}'.

\item \verb|\tty| should be `y' if the encoding is \TeX\ typewriter
   (cmtt) encoding, and `n' otherwise.

\item \verb|\currency| should be the name of the currency glyph, either
   `sterling' or `dollar'.
\end{itemize}
These should all expand in the mouth, otherwise you may get error
messages!

For example, to get the standard upper and lower case font, you should
define:
\begin{verbatim}
   \setcommand\lc#1#2{#2}
   \setcommand\uc#1#2{#1}
   \setcommand\lclig#1#2{#2}
   \setcommand\uclig#1#2{#1}
   \setcommand\digit#1{#1}
   \setcommand\tty{n}
   \setcommand\currency{dollar}
\end{verbatim}
To get a caps and small caps font with old style digits and letter
spacing, you should define:
\begin{verbatim}
   \setcommand\lc#1#2{#1small}
   \setcommand\uc#1#2{#1}
   \setcommand\lclig#1#2{#2small}
   \setcommand\uclig#1#2{#1spaced}
   \setcommand\digit#1{#1oldstyle}
   \setcommand\tty{n}
   \setcommand\currency{dollar}
\end{verbatim}
To get an all-caps font with medium-cap composite letters and letter
spacing, you should define:
\begin{verbatim}
   \setcommand\lc#1#2{#1}
   \setcommand\uc#1#2{#1}
   \setcommand\lclig#1#2{#1spaced}
   \setcommand\uclig#1#2{#1spaced}
   \setcommand\digit#1{#1}
   \setcommand\tty{n}
   \setcommand\currency{dollar}
\end{verbatim}
This document describes the upper and lower case encoding.

\comment{\section{The encoding}
   There are 130 glyphs in this encoding.  128 of these are in Knuth's CM
   encoding, and the other two are `\l' and `\L', which are composite
   letters in CM, but are single glyphs in almost every other font.}
