\section{Test case conversions of Greek letters}
This document tests the combination of \verb|MakeUppercase| and Greek.
\makeatletter
It is compiled with \texengine, format version \fmtversion{} patch-level
\patch@level{} and the L3 programming layer from \ExplFileDate{}.
\makeatother
The \verb|\greekfontencoding| is \greekfontencoding.

The lowercase of \langGreek{Σ} is the «auto-sigma»
(\verb|\textautosigma|): \langGreek{ΣΣ $\mapsto$ \MakeLowercase{ΣΣ}}.
Add a ZWNJ or use the \verb|\noboundary| macro to prevent conversion to
final sigma: \langGreek{\MakeLowercase{ΣΣ}} (works only with "old"
(pre-2022) \verb|\MakeLowercase|).

% With TeXLive 2020 (old \verb|\Makeuppercase|),

% Uppercase of character ';' 0x37E GREEK QUESTION MARK is a semicolon
% which is mapped to '·' 0x387 GREEK ANO TELEIA by LGR. :(
%
% Accents dropped with MakeUppercase (not for single letter ή) :)
% TODO: how to treat MakeUppercase of a single captial «΄Η»?
%
% Should the “educational”/“Latin” accents *macron* and *breve* (*vrachy*)
% be kept (they stay above capital letters similar to the dialytika,
% they are kept by Apostolos Syropoulos' “xgreek” package and in babel-greek
% “since ages”) or dropped (they are optional even in lowercase or titlecase
% and dropped for the entry by the English wiktionary).
% https://en.wiktionary.org/wiki/Wiktionary:About_Ancient_Greek#Diacritics_and_accentuation
%
% Spacing prosgegrammeni (ι) turned to capital Iota. (minor)
%
% Spacing single diacritics are kept. (irrelevant, OK)
% Spacing combining diacritics are mapped to single diacritics. (irrelevant)
%
% Auto-Hiatus: ἀυπνία → ΑΥΠΝΙΑ (missing dialytika on the Upsilon).
% With pdfLaTeX and LGR, a ZWNJ or the ``\noboundary`` macro can be used to
% prevent conversion of trailing Σ to a final sigma ς by ``\MakeLowercase``.
% This does not work with Unicode fonts (XeTeX/LuaTeX).
% With XeTeX and Unicode fonts,
\subsubsection{hiatus}
Tonos and dasia mark a \emph{hiatus} (break-up of a diphthong) if placed on
the first of two consecutive vowels (άι, άυ, έι, ἀυ, ἄι, ἄυ, ἔι).
A dialytika must be placed on the second vowel if they are dropped.
Since the 2022/06 LaTeX release, it works with monotonic Unicode literals
(since 2023/02/10] also some polytonic but fails with psili):
\begin{quote}
\selectlanguage{greek}
\newcommand*{\hiatest}{άι, άυ, έι, ἄι, ἄυ, ἔι, ἀυ}
\hiatest{} $\mapsto$ \MakeUppercase{\hiatest}
\end{quote}
Example \foreignlanguage{greek}{ἀυπνία $\mapsto$ \MakeUppercase{ἀυπνία}}
(missing dialytika on the Upsilon).

\ifdefined \UnicodeEncodingName % set by LaTeX for Unicode-aware engines
\textbf{Warning:}
As the uc/lccode re-definitions are not performed when Unicode fonts are
used, the accents are not dropped from upcased Latin transliterations.
Accent macros work fine also in Latin transliterations with Xe/LuaTeX.

With LGR, the lowercase of \ensuregreek{Σ} is the «auto-sigma»
(\verb|\textautosigma|): \ensuregreek{ΣΣ $\mapsto$ \MakeLowercase{ΣΣ}}.
Add a ZWNJ or use the \verb|\noboundary| macro to prevent conversion to
final sigma: \ensuregreek{\MakeLowercase{ΣΣ}}.
The lowercase of GREEK LETTER STIGMA \ensuregreek{Ϛ} is
\ensuregreek{\MakeLowercase{Ϛ}}, not \verb|\textvarstigma|%
\ifdefined \UnicodeEncodingName \else
(\ensuregreek\textvarstigma)%

\subsection{Greek extended}
