+\section{Discussion}
+
+\subsection{Differences between literal input and LICRs}
+
+Under pdfTeX and XeTeX, all input variants select pre-composed characters
+if possible (\href{https://www.unicode.org/reports/tr15/}{Unicode
+normalization} NFC).
+Under luaTeX, accent macros on a literal character are printed using
+combining diacritical marks. This leads to suboptimal placement of
+diacritics with many fonts, often resulting in illegible output.
+
+\subsubsection{Upcasing}
+
+Up to 2022, diacritics were dropped from Greek letters in UPPERCASE in any
+locale. The new \cs{MakeUppercase} implementation follows the Unicode
+standard, where dropping diacritics is a feature of the Greek locale (``el'').
+
+However, ``named'' accent macros with Greek names behave according to Greek
+typsetting rules in \emph{all} locales.
+The current implementation also drops diacritics input via standard accent
+macros in documents that declare the Greek language with Babel.
+
+Apart from the diacritical marks native to Greek itself, linguists also
+regularly mark vowel length with macrons (¯) and breves (˘).
+The length markers are used in dictionaries and textbooks
+but not part of the Greek orthography. There is no established praxis
+regarding their handling in uppercase. LaTeX keeps them but
+the \href{https://icu.unicode.org/design/case/greek-upper}{%
+Unicode reference implementation} drops them.
+
+Greek stand-alone diacritics are dropped by \cs{MakeUppercase} if input via
+accent macros (e.g. \cs{accdialytika} or \cs{'>}).
+
+
+\subsubsection{Sigma, final sigma, and ``autosigma''}
+
+There are two variants of the lower case letter \emph{sigma}.
+
+The lowercasing \ensuregreek{Σ} should select a final sigma at the end of a
+word: \ensuregreek{ΣΣ $\mapsto$ \MakeLowercase{ΣΣ}}.
+
+Since 2022, \cs{MakeLowercase} selects the correct sigma variant for a
+literal Sigma under Xe/LuaTeX, too.
+
+The \cs{textSigma} \emph{macro} is mapped to \verb|\textautosigma| which
+under 8-bit TeX prints the sigma variant according to its position but,
+unfortunately, fails with Unicode fonts:
+\ensuregreek{\textSigma\textSigma{} → \MakeLowercase{\textSigma\textSigma}}.
+
+In LGR, you can add a ZWNJ or use the \verb|\noboundary| macro to prevent the
+conversion to a final sigma: \ensuregreek{\MakeLowercase{ΣΣ‌}}.
+
+
+\subsubsection{%
+ The one-letter word
+ \ifx\captionsgreek\captionspolutonikogreek
+ \emph{ἢ}
+ \else
+ \emph{ή}
+ \fi
+ (or)}
+
+For disambiguation, the Greek word \emph{or} (ή / ἢ) keeps diacritics in
+UPPERCASE:
+
+\TestUppercase{ή Ή ἢ Ἢ ἤ Ἤ }.\footnote{
+ TODO: The polytonic variant with dasia and oxia used in
+ ἢ … ἤ (\emph{either … or}) drops diacritics!
+ By mistake, omission, or intent?}
+
+\noindent However, eta drops diacritics if it is part of a word:
+\TestUppercase{ήτοι, Ήτοι, επιταγή ἤτοι, Ἤτοι}.%
+\footnote{TODO: It seems the test is only for whitespace on both sides:
+ \TestUppercase{ή, Ή. ἢ; Ἢ}
+ }
+
+\smallskip\noindent
+TODO: The 2022 MakeUppercase handles this for literal input.
+Currently, this feature is not supported with other input methods.
+
+
+\subsection{Case conversion if the locale is \emph{not} Greek}
+
+In order to fix upcasing for Greek, babel-greek maps standard accent macros
+to ``capital'' versions.\footnote{%
+ In case of problems, these mappings can be disabled with the
+ \texttt{local-MakeUppercase-fixes} language modifier.}
+The default expansion ensures that accents are
+kept on Latin letters: \'a \`a \~a \"a → \MakeUppercase{\'a \`a \~a \"a}.%
+\footnote{If the Language is set to Greek, this works unless the font encoding
+ is 8-bit LGR (where Latin letters are interpreted as Latin transliteration
+ anyway): \Greek{\'u \`u \~u \"u \ensureascii{\'u} →
+ \MakeUppercase{\'u \`u \~u \"u \ensureascii{\'u}}}.}
+
+Some characters from the “Greek and Coptic” and “Greek extended” Unicode
+blocks have no pre-composed uppercase equivalent. Since 2022, upcasing them
+led to compiling errors under pdfLaTeX.
+This is fixed in the 2023 LaTeX release by mapping the affected characters
+to macro representations before case conversions:
+with pdfLaTeX, diacritics are dropped from literal characters without
+pre-composed uppercase equivalent also if the text language is \emph{not}
+Greek, with Xe/LuaTeX, combining charactes are used (and may overlap with
+the base letter).
+
+ΐΰὐὒὔὖᾶᾷῆῇῒΐῖῗῢΰῤῦῧῶῷ → \MakeUppercase{ΐΰὐὒὔὖᾶᾷῆῇῒΐῖῗῢΰῤῦῧῶῷ}
+
+
+\subsection{Symbol variants}
+
+Several Greek letters have alternative representations which may have a
+different semantic in a mathematical context.
+Unicode reserves code points for the alternative representations
+(naming them ``symbol'' as opposed to ``letter'').
+Some of these symbols are available as \cs{var<name>} macros in TeX's
+mathematical mode.
+
+In text, they are considered typographical variants without special
+meaning. The 8-bit LGR font encoding does not allocate code points for them.
+\emph{Babel-greek} and the \emph{%
+\href{http://mirrors.ctan.org/language/greek/greek-fontenc/textalpha-doc.pdf}
+{textalpha}} package provide the \texttt{normalize-symbols} option
+(ignored with Xe/LuaTeX) that is also used in this test document.
+
+\smallskip\noindent

+ π\textpi \textvarpi \textpisymbol ϖ

+}
+
+\noindent
+No case change
+\begin{quote}

+\end{quote}
+%
+MakeUppercase selects the matching capital letter:
+
+\begin{center}
+ \Greek{\MakeUppercase{\symbolvariants}}
+\end{center}
+
+\noindent
+MakeLowercase selects the lowercase letter (not the symbol):
+\begin{quote}
+ \Greek{
+ \MakeLowercase{\textBeta Β \textEpsilon Ε
+ \textTheta Θ \textThetasymbol \textvarTheta ϴ
+ \textKappa Κ \textPi Π \textRho Ρ \textPhi Φ}}.
+\end{quote}
+LGR provides two lowercase variants of the archaic letter \emph{stigma}.
+Both map to GREEK LETTER STIGMA \ensuregreek{Ϛ}.
+
+The lowercase of \ensuregreek{Ϛ} is \ensuregreek{\MakeLowercase{Ϛ}}
+(\verb|\textstigma|), not \verb|\textvarstigma|%
+\ifdefined \UnicodeEncodingName \else
+ (\ensuregreek\textvarstigma)%
+\fi .
+
+
+\subsection{Hiatus}
+
+Tonos and psili mark a \emph{hiatus} (break-up) if placed on
+the first of two vowels that would otherwise form a diphthong.
+A dialytika must be placed on the second vowel if they are dropped:
+
+\begin{quote}
+ \TestUppercase{άι άυ έι ἄι ἄυ ἔι ἀυ} (literal)
+
+ \TestUppercase{\acctonos\textalpha\textiota{}
+ \acctonos\textalpha\textupsilon{}
+ \acctonos\textepsilon\textiota{}
+ \accpsilioxia\textalpha\textiota{}
+ \accpsilioxia\textalpha\textupsilon{}
+ \accpsilioxia\textepsilon\textiota{}
+ \accpsili\textalpha\textupsilon{}
+ } (named+LICR)
+
+ \TestUppercase{\'\textalpha\textiota{} \'\textalpha\textupsilon{}
+ \'\textepsilon\textiota{} \>'\textalpha\textiota{}
+ \>'\textalpha\textupsilon{} \>'\textepsilon\textiota{}
+ \>\textalpha\textupsilon{}
+ } (short+LICR)
+
+ \TestUppercase{\ux{\'αι \'αυ \'ει \>'αι \>'αυ \>'ει \>αυ}
+ {\'ai \'au \'ei \>'ai \>'au \>'ei \>au}
+ } (short+\ux{literal}{transliteration})
+
+ \TestUppercase{\ux{\'>αι \'>αυ \'>ει \'\>αι \'\>αυ \'\>ει}
+ {\'>ai \'>au \'>ei \'\>ai \'\>au \'\>ei}
+ } (short+\ux{literal}{transliteration}, reversed)
+\end{quote}
+The ``hiatus feature'' does not work with the LGR ``input ligatures''.
+Support for monotonic literal charactes came with the 2022
+\cs{MakeUppercase} implementation changes.
+Since 2023 it also works with polytonic literals (\TestUppercase{ἀυπνία}).
+
+% Very occasionally, one will see "internal breathings" in transliterations of
+% foreign names, e.g., \TestUppercase{Ἀβραἅμ} for Abraham.
+
+% The remainder is only relevant with 8-bit TeX:

+
+Downcasing should keep diacritics (of course, it cannot regenerate
+``manually" dropped ones):
+\Greek{'A \"I \"U \~<A $\mapsto$ \MakeLowercase{\'A \"I \"U \~<A}}.
+
+
+\subsection{Problems with the Latin transliteration}
+
+\begin{itemize}
+\item
+ With monotonic Greek or if \cs{greekfontencoding} is not LGR, the
+ tilde \verb|~| keeps its default expansion as no-break space (NBSP) and
+ transliterations involving \verb|~| fail.
+ If the \texttt{greek} language is loaded with Babel, the tilde accent
+ \verb|\~| as well as combined accents involving the tilde work in all
+ language variants.
+
+\item
+ In order to drop accents from input using the Latin transliteration, the
+ characters ', `, \~{}, <, and > are suppressed in uppercase. This affects
+ other uses of these characters:
+ \begin{quote}
+ \TestUppercase{\lgrfont{(( ` ' ~ < > ))}}\qquad
+ \TestUppercase{\lgrfont{``x''}}
+ \end{quote}
+ Workaround: use literal typographical quote characters or ``french'' quotes:
+ \begin{quote}
+ \TestUppercase{\lgrfont{‘x’}} \qquad
+ \TestUppercase{\lgrfont{((x))}}
+ \end{quote}
+ To keep side-effects to a minimum, breathings, combined accents and
+ varia are dropped only with the language variants \emph{polutoniko}
+ or \emph{ancient} as they are not required with monotonic Greek
+ (the current language variant is \GreekLanguageVariant).
+
+\item
+ The uppercase of spacing composite diacritics including
+ a dialytika \verb|"~ "` "'| appears as apostrophe, as a single \verb|"|
+ stands for an apostrophe in the LGR transliteration if followed by a
+ space or empty character.
+
+\item
+ With the pre-2022 \cs{MakeUppercase}, the input order is important
+ in combined accents involving the dialytika, e.g.,
+ \verb|'"i "'i| is upcased \Greek{'"i "'i → \MakeUppercase{'"i "'i}}.

-
-This document tests support for the Greek non-standard LGR fonts with the
-contributed packages \emph{greek-fontenc} and \emph{greek-inputenc}.
-It is compiled with the \textbf{\uppercaseversion{}} \verb|\MakeUppercase|
-version.
-
-The LGR font encoding definition file \texttt{lgrenc.def} defines LICR
-macros for all non-ASCII characters in the LGR font encoding and loads
-definitions shared with the TU font encoding from
-\texttt{greek-fontenc.def}.
-
-In addition to the LICR, Greek letters can also be input via a Latin
-transliteration.
-
-Greek accent macros have names starting with \verb|\acc| followed by the
-Greek accent name as used in the Unicode standard (e.g. \verb|\acctonos|).
-The standard symbol accents \verb|\' \` \~ \"| should behave according to
-Greek typography if used with Greek letters.
-
-Apart from the diacritical marks native to Greek itself, linguists also
-regularly mark vowel length with macrons (¯) and breves (˘).
-There is no established praxis regarding their handling in uppercase.
-
-The \emph{textalpha} or \emph{alphabeta} packages define the symbol macros
