\section*{Greek Unicode with 8-bit TeX and \emph{inputenc}}

\begin{abstract}
  Small test of Unicode input for Greek letters.
\end{abstract}

Without the "textalpha" or "alphabeta" packages, Greek Unicode characters
must be wrapped in \verb+\ensuregreek{}+, \verb+\textgreek{}+, or\\
\verb+\foreignlanguage{greek}{}+ or follow the declarations
\verb+\greekscript+, \verb+\greektext+, or \verb+\setlanguage{greek}+ to set
the correct font encoding (LGR).

\begin{quote}
  \greekscript
  Τί φήις; Ἱδὼν ἐνθέδε παῖδ’ ἐλευθέραν
  τὰς πλησίον Νύμφας στεφανοῦσαν, Σώστρατε,
  ἐρῶν άπῆλθες εὐθύς;
\end{quote}

The MIKRO SIGN and OHM SIGN characters are set up by textcomp for
any font encoding:
\begin{quote}
  With a a 50\,kΩ resistor, the current is 20\,µA.
\end{quote}
However, if the similar looking Greek Unicode characters are used, LGR is
required for GREEK CAPITAL LETTER OMEGA. On the other hand, GREEK SMALL
LETTER MU works in any font encoding because it translates to
\verb+\textmu+, the LICR also used by textcomp for the MICRO SIGN.
\begin{quote}
  With a a 50\,k\ensuregreek{Ω} resistor, the current is 20\,μA.
\end{quote}


\section{Warning: unsafe ASCII input}

LGR is no ``standard font encoding''. Latin characters and some other ASCII
symbols are mapped to Greek equivalents if LGR is the active font encoding.
(See
\href{http://mirrors.ctan.org/language/babel/contrib/greek/usage.pdf}{usage.pdf}
for a description of this Latin-Greek transliteration.)

This means you need an explicit language and/or font-encoding switch for
Latin words and abbreviations in Greek text, e.g., not
\foreignlanguage{greek}{((ηία αντίσταση 750-kΩ))} but
\foreignlanguage{greek}{((ηία αντίσταση 750-\textlatin{k}Ω))}

Special care is also required with the question mark characters:
\begin{itemize}
  \item The Unicode standard says: ``character 003B SEMICOLON, and not 
  	037E GREEK QUESTION MARK, is the preferred character for a `Greek
	question mark' (erotimatiko)'',
  \item The LGR font encoding maps a SEMICOLON to a middle dot (ano teleia),
	while the Latin question mark ``?'' is mapped to the erotimatiko.
\end{itemize}
As a result, only the deprecated character 037E GREEK QUESTION MARK works
with both, Xe/LuaTeX and 8-bit TeX.

With the \emph{textalpha} package's ``keep-semicolon'' option, the 
SEMICOLON character can be used for the erotimatiko also with LGR encoded
fonts.


\section{Supported Characters}

Unicode definitions exist for all non-ASCII characters that can be rendered
with an LGR-encoded font.

\section{Test up/downcasing}

Capital Greek letters have diacritics (except the dialytika) to the left
(instead of above) and drop them in uppercase, e.g.
\foreignlanguage{greek}{μαΐστρος $\mapsto$ \MakeUppercase{μαΐστρος}}.

Tonos and dasia on the first vowel of a diphthong (\ensuregreek{άι, άυ, έι})
imply a \emph{hiatus}. A dialytika must be placed on the second
vowel if they are dropped (\ensuregreek{\MakeUppercase{\'ai, \'au, \'ei}}).

The auto-hiatus feature in lgrxenc.def works with the Latin
transcription and with character-macros (%
\ensuregreek{\MakeUppercase{%
  \'ai,
  \'\textalpha \textupsilon,
  \'\textepsilon \textiota
}})
and also if the first character is wrapped in \verb+\ensuregreek+ (as done by
the lgrenc.dfu definition for accented characters) or a literal Unicode
character
(\ensuregreek{\MakeUppercase{%
  \ensuregreek{\'\textalpha}\textiota,
  ά\textupsilon,
  ά\textiota
}})
but not if the second character of the diphthong is a Unicode literal
(\ensuregreek{\MakeUppercase{%
  \'\textalpha ι,
  άυ,
  \'\textepsilon ι
}}).

Therefore, the diaresis is missing in the following examples:
\ensuregreek{άυλος  $\mapsto$ \MakeUppercase{άυλος},
           ἄυλος  $\mapsto$ \MakeUppercase{ἄυλος},
           μάινα  $\mapsto$ \MakeUppercase{μάινα},
           κέικ,  $\mapsto$ \MakeUppercase{κέικ},
           ἀυπνία $\mapsto$ \MakeUppercase{ἀυπνία}}.

Fixing this shortcoming requires knowledge of what
\verb+\LGR@ifnextchar+ ``sees'' when the next character is an upcased
Unicode literal.

As an ugly workaround, use \verb+\textiota+ resp. \verb+\textupsilon+
for the character that should get the diaresis:
\ensuregreek{ἀ\textupsilon{}πνία $\mapsto$ \MakeUppercase{ἀ\textupsilon{}πνία}}.



The following subsections test MakeUppercase and MakeLowercase with all
characters defined in lgrenc.dfu:

\subsection{Greek and Coptic}

\newcommand{\GreekAndCoptic}{ʹ͵ͺ; ΄ ΅Ά·ΈΉΊΌΎΏΐΑΒΓΔΕΖΗΘΙΚΛΜΝΞΟΠΡΣΤΥΦΧΨΩΪΫϘϚϜϠ}
\newcommand{\greekandcoptic}{άέήίΰαβγδεζηθικλμνξοπρςστυφχψωϊϋόύώϙϛϝϟϡ}

Characters of the Greek and Coptic Unicode Block:
\begin{quote}
  \selectlanguage{greek}
  \GreekAndCoptic\\

\end{quote}
MakeUppercase:
\begin{quote}
  \selectlanguage{greek}
  \MakeUppercase{\GreekAndCoptic}\\
  \MakeUppercase{\greekandcoptic}
\end{quote}
Letters and ypogegrammeni upcased, tonos dropped, dialytika kept.

There is no capital Koppa in LGR, therefore \ensuregreek{ϟ} is left unchanged
with MakeUppercase.


MakeLowercase:

\begin{quote}
  \selectlanguage{greek}
  \MakeLowercase{\GreekAndCoptic}\\
  \MakeLowercase{\greekandcoptic}
\end{quote}

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}}.
