+\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.
+
+\tableofcontents
+
+
+\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{\ }

+\accdialytika{\ } \accperispomeni{\ }
+\accdialytikatonos{\ }\ \accdialytikavaria{\ }\ \accdialytikaperispomeni{\ }\
+\accdasiaoxia{\ }\ \accdasiavaria{\ }\ \accdasiaperispomeni{\ }\
+\accpsilioxia{\ }\ \accpsilivaria{\ }\ \accpsiliperispomeni{\ }

+\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.
+
+

+\textdexiakeraia{} textdexiakeraia \\ % ʹ
+\textaristerikeraia{} textaristerikeraia \\ % ͵
+\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.
