\title{Test LICR macros in LuaTeX's 8-bit compatibility mode}
\author{G\"unter Milde}
\date{2023/03/08}
\maketitle

This document tests the compatibility of ``luainputenc'' and the Greek font
setup for TU and PU. It uses only ASCII input.

See the source \texttt{test-inputenc.tex} for the input used in the examples.

\section{LICR input%
         \label{licr}}

The LaTeX internal character representation (LICR) is a verbose, fail-safe
7-bit ASCII encoding that can be used unaltered under both, 8-bit TeX (with
any ASCII-compatible input encoding) and XeTeX/LuaTeX.
Use cases are macro definitions and generated text.


\subsection{Greek alphabet}

Greek letters via LICR macros:
\begin{quote}
  \textAlpha{} \textBeta{} \textGamma{} \textDelta{} \textEpsilon{}
  \textZeta{} \textEta{} \textTheta{} \textIota{} \textKappa{}
  \textLambda{} \textMu{} \textNu{} \textXi{} \textOmicron{} \textPi{}
  \textRho{} \textSigma{} \textTau{} \textUpsilon{} \textPhi{}
  \textChi{} \textPsi{} \textOmega{}

  \textalpha{} \textbeta{} \textgamma{} \textdelta{} \textepsilon{}
  \textzeta{} \texteta{} \texttheta{} \textiota{} \textkappa{}
  \textlambda{} \textmu{} \textnu{} \textxi{} \textomicron{} \textpi{}
  \textrho{} \textsigma{} \texttau{} \textupsilon{}
  \textphi{} \textchi{} \textpsi{} \textomega{}
\end{quote}
The small sigma is set with a different
glyph if it ends a word:
\begin{quote}
  \textsigma{}       \verb|textsigma|\\
  \textfinalsigma{}  \verb|textfinalsigma| or \verb|textvarsigma|
\end{quote}
%
The \verb|\textautosigma| macro (which automatically chooses the glyph
according to the position) does not work with Unicode fonts (Xe/LuaTeX, font
encoding TU).


\subsection{Diacritics}

Greek accents are
tonos = oxia, varia, psili, dasia, dialytika, and perispomeni.

Greek diacritics can be input by named macro or symbol macro:
\begin{quote}
  \acctonos\textalpha       \'\textalpha{}  \acctonos       x\'x
  \accvaria\textalpha       \`\textalpha{}  \accvaria       x\`x
  \accdialytika\textiota{}  \"\textiota{}   \accdialytika   x\"x
  \accperispomeni\textalpha \~\textalpha{}  \accperispomeni x\~x
  \accpsili\textalpha       \>\textalpha{}  \accpsili       x\>x
  \accdasia\textalpha       \<\textalpha{}  \accdasia       x\<x
\end{quote}
%
Combining diacritics were misplaced with the 2021 version of LuaTeX in 8-bit
compatibility mode. This can be solved by selecting the "Harfbuzz" renderer
(see the source).
\begin{quote}
  \accdasia`\textepsilon{} \accpsili'\textepsilon{} \~>\textupsilon{}
  \~>\textalpha\ypogegrammeni{} \~<\textalpha\ypogegrammeni
\end{quote}
%
Diacritics as spacing characters:

with empty argument:
\ensuregreek{
\acctonos{} \accoxia{} \accvaria{}
\accpsili{} \accdasia{}
\accdialytika{} \accperispomeni{}
\accdialytikatonos{} \accdialytikavaria{} \accdialytikaperispomeni{}
\accdasiaoxia{} \accdasiavaria{} \accdasiaperispomeni{}
\accpsilioxia{} \accpsilivaria{} \accpsiliperispomeni{}
}

with space as argument:
\ensuregreek{
\acctonos{ } \accoxia{ } \accvaria{ }
\accpsili{ } \accdasia{ }
\accdialytika{ } \accperispomeni{ }
\accdialytikatonos{ } \accdialytikavaria{ } \accdialytikaperispomeni{ }
\accdasiaoxia{ } \accdasiavaria{ } \accdasiaperispomeni{ }
\accpsilioxia{ } \accpsilivaria{ } \accpsiliperispomeni{ }
}

with protected space:
\ensuregreek{
\acctonos{\ } \accoxia{\ } \accvaria{\ }
\accpsili{\ } \accdasia{\ }
\accdialytika{\ } \accperispomeni{\ }
\accdialytikatonos{\ }\ \accdialytikavaria{\ }\ \accdialytikaperispomeni{\ }\
\accdasiaoxia{\ }\ \accdasiavaria{\ }\ \accdasiaperispomeni{\ }\
\accpsilioxia{\ }\ \accpsilivaria{\ }\ \accpsiliperispomeni{\ }
}

with nobreakspace:
\ensuregreek{
\acctonos{\nobreakspace} \accoxia{\nobreakspace} \accvaria{\nobreakspace}
\accpsili{\nobreakspace} \accdasia{\nobreakspace}
\accdialytika{\nobreakspace} \accperispomeni{\nobreakspace}
\accdialytikatonos{\nobreakspace}\ \accdialytikavaria{\nobreakspace}\
\accdialytikaperispomeni{\nobreakspace}\ \accdasiaoxia{\nobreakspace}\
\accdasiavaria{\nobreakspace}\ \accdasiaperispomeni{\nobreakspace}\
\accpsilioxia{\nobreakspace}\ \accpsilivaria{\nobreakspace}\
\accpsiliperispomeni{\nobreakspace}
}

\subsubsection{mute iota}

The mute iota is input after the base letter.

\begin{itemize}
\item \verb|\ypogegrammeni| following a Greek letter sets a sub-iota
  (corresponding to COMBINING GREEK YPOGEGRAMMENI),
  e.g. \ensuregreek{\textalpha\ypogegrammeni{}}.

  In Unicode, a GREEK CAPITAL LETTER ... followed by
  COMBINING GREEK YPOGEGRAMMENI is normalized to
  GREEK CAPITAL LETTER ... WITH [... AND] PROSGEGRAMMENI,
  if a corresponding letter exists in the Unicode standard.
  In LGR fonts, this is implemented via a ligature definition
  (set the Babel language or wrap in \verb|\ensuregreek|):
  \ensuregreek{\textAlpha\ypogegrammeni{}} but
  \ensuregreek{\textLambda\ypogegrammeni{}}.

  The shape and position of the mute iota with pre-composed capital letters
  depends on the selected font, both sub-iota and adscript iota are possible.

\item \verb|\prosgegrammeni| sets an adscript iota (GREEK PROSGEGRAMMENI),
  e.g. \textAlpha\prosgegrammeni{}.
  In Unicode fonts the prosgegrammeni is spaced similar to the letter iota.
  In the CB Greek fonts, the only visible difference to the pre-composed
  characters is a slightly increased spacing.

  Copy/Paste may convert the adscript iota to a small letter iota!

\end{itemize}
Ypogegrammeni and prosgegrammeni following matching/not-matching base character
(unchanged, lowercase, uppercase):
\begin{quote}
  \greekscript
  \textAlpha\ypogegrammeni \textAlpha\prosgegrammeni{}
  \MakeLowercase{\textAlpha\ypogegrammeni \textAlpha\prosgegrammeni}
  \MakeUppercase{\textAlpha\ypogegrammeni \textAlpha\prosgegrammeni}

  \textLambda\ypogegrammeni \textLambda\prosgegrammeni{}
  \MakeLowercase{\textLambda\ypogegrammeni \textLambda\prosgegrammeni}
  \MakeUppercase{\textLambda\ypogegrammeni \textLambda\prosgegrammeni}

  \textalpha\ypogegrammeni \textalpha\prosgegrammeni{}
  \MakeLowercase{\textalpha\ypogegrammeni \textalpha\prosgegrammeni}
  \MakeUppercase{\textalpha\ypogegrammeni \textalpha\prosgegrammeni}
\end{quote}

Using \verb|\ypogegrammeni| for the mute iota with both, small and capital
letters usually gives better results.

\end{quote}

% \subsubsection{Ancient Greek Numbers}
%
% Ancient Greek Numbers are missing in most fonts (including Libertine and
% Deja Vu). The “FreeSerif” font works fine:
% \begin{quote}
% \textpentedeka    % GREEK ACROPHONIC ATTIC FIFTY
% \textpentehekaton % GREEK ACROPHONIC ATTIC FIVE HUNDRED
% \textpenteqilioi  % GREEK ACROPHONIC ATTIC FIVE THOUSAND
% \textpentemuria   % GREEK ACROPHONIC ATTIC FIFTY THOUSAND
% \end{quote}

\subsubsection{generic text symbols}

LICR macros for some symbols from the 8-bit font encoding LGR that are not
confined to Greek but not defined in \texttt{tuenc.def} [2018/08/11 v2.0j].

\begin{quote}
  \textsemicolon{} textsemicolon\\
  \textmicro{} textmicro \\
  \textschwa{} textschwa
\end{quote}
The SI unit prefix MICRO SIGN is not upcased with MakeUppercase:

\begin{quote}
  textmu: \textmu{} $\mapsto$ \MakeUppercase{\textmu} but
  textmicro: \textmicro{} $\mapsto$ \MakeUppercase{\textmicro}.
\end{quote}

\section{Greek in section headings}

The packages \emph{textalpha} and \emph{alphabeta} as well as
\emph{babel-greek}, add hyperref support for LICR input with
non-standard accents or combined diacritics.
