[2013/07/18 0.1.1 Greek LICRs for XeTeX and LuaTeX]

Based on xunicode, lgrenc.def and lgrenc.dfu.

0.1.1

bugfix: wrong breathings psilioxia -> dasiaoxia

Requires XeTeX or LuaTeX and a font with Greek characters. See test-xunicode.tex and test-xunicode.pdf for usage details and example.

xunicode.sty defines several commands for the declaration of UTF characters, composites and accents. These are (sparsely) documented in the source. Unfortunately, they do not work seamless with the standard NFSS commands described in the fntguide. Therefore, some declarations are done twice: for fontenc and for xunicode (xunicode itself uses dummy declarations for the OT1 encoding).

Greek Diacritics

Define “named macros” for simple and combined diacritics.

Greek alias names for standard accents:

\DeclareTextCommand{\acctonos}{\LastDeclaredEncoding}{\@tabacckludge'}
\DeclareTextCommand{\accvaria}{\LastDeclaredEncoding}{\@tabacckludge`}
\DeclareTextCommand{\accdialytika}{\LastDeclaredEncoding}{\@tabacckludge"}
\DeclareTextCommand{\accperispomeni}{\LastDeclaredEncoding}{\@tabacckludge~}

Breathings:

\DeclareTextCommand{\accpsili}{\LastDeclaredEncoding}[1]{#1\char"0313 } % ψιλή spiritus lenis (smooth breathing)
\DeclareTextCommand{\accdasia}{\LastDeclaredEncoding}[1]{#1\char"0314 } % δασεῖα spiritus asper (rough breathing)
\DeclareTextCommand{\>}{\LastDeclaredEncoding}{\accpsili}
\DeclareTextCommand{\<}{\LastDeclaredEncoding}{\accdasia}
\DeclareEncodedCompositeCharacter{\LastDeclaredEncoding}{\accpsili}{0313}{02BC} % COMBINING COMMA ABOVE = Greek psili, smooth breathing mark
\DeclareEncodedCompositeCharacter{\LastDeclaredEncoding}{\accdasia}{0314}{02BD} % COMBINING REVERSED COMMA ABOVE = Greek dasia, rough breathing mark

The COMBINING GREEK KORONIS is a legacy character, discarded in favour of COMBINING COMMA ABOVE

Sub-iota:

% \ypogegrammeni is a postfix accent (ligature in LGR)
\DeclareUTFcharacter[\LastDeclaredEncoding]{x0345}{\ypogegrammeni} % COMBINING GREEK YPOGEGRAMMENI

Combined diacritics:

% \DeclareTextCommand{\accdialytikatonos}{\LastDeclaredEncoding}{\textdieresisacute} % Greek alias
% \DeclareTextCommand{\accdialytikavaria}{\LastDeclaredEncoding}{\textdieresisgrave}
\DeclareTextCommand{\accdialytikatonos}{\LastDeclaredEncoding}[1]{#1\char"0308 \char"0301 }
\DeclareTextCommand{\accdialytikavaria}{\LastDeclaredEncoding}[1]{#1\char"0308 \char"0300 }
\DeclareTextCommand{\accdialytikaperispomeni}{\LastDeclaredEncoding}[1]{#1\char"0308 \char"0342 }

\DeclareTextCommand{\accdasiaoxia}{\LastDeclaredEncoding}[1]{#1\char"0314 \char"0301 }
\DeclareTextCommand{\accdasiavaria}{\LastDeclaredEncoding}[1]{#1\char"0314 \char"0300 }
\DeclareTextCommand{\accdasiaperispomeni}{\LastDeclaredEncoding}[1]{#1\char"0314 \char"0342 }

\DeclareTextCommand{\accpsilioxia}{\LastDeclaredEncoding}[1]{#1\char"0313 \char"0301 }
\DeclareTextCommand{\accpsilivaria}{\LastDeclaredEncoding}[1]{#1\char"0313 \char"0300 }
\DeclareTextCommand{\accpsiliperispomeni}{\LastDeclaredEncoding}[1]{#1\char"0313 \char"0342 }

xunicode special commands for accents with combining Unicode character(s):

According to the definition and usage in xunicode.sty, \DeclareEncodedCompositeAccents should set up accents by combining two combining characters. Unfortunately this does not seem to work: one of the combining characters is missing (see test-xunicode.tex). However, as for all letters that use the combining accents pre-composed characters are selected (via composite definitions below) this should not matter in actual use:

% The COMBINING DIALYTIKA TONOS is discarded and not well supported by fonts:
% \DeclareEncodedCompositeCharacter{\LastDeclaredEncoding}{\accdialytikatonos}{0344}{0385} % COMBINING GREEK DIALYTIKA TONOS / GREEK DIALYTIKA TONOS
% If Dialytika-Tonos and Dialytika-Varia are defined as alias for \textdieresisacute,
% and \textdieresisgrave, they are already set up for xunicode.
\DeclareEncodedCompositeAccents{\LastDeclaredEncoding}{\accdialytikatonos}{0301}{0308}
\DeclareEncodedCompositeAccents{\LastDeclaredEncoding}{\accdialytikavaria}{0300}{0308}
\DeclareEncodedCompositeAccents{\LastDeclaredEncoding}{\accdialytikaperispomeni}{0342}{0308}

\DeclareEncodedCompositeAccents{\LastDeclaredEncoding}{\accdasiaoxia}{0314}{0301}
\DeclareEncodedCompositeAccents{\LastDeclaredEncoding}{\accdasiavaria}{0314}{0300}
\DeclareEncodedCompositeAccents{\LastDeclaredEncoding}{\accdasiaperispomeni}{0314}{0342}

\DeclareEncodedCompositeAccents{\LastDeclaredEncoding}{\accpsilioxia}{0301}{0313}
\DeclareEncodedCompositeAccents{\LastDeclaredEncoding}{\accpsilivaria}{0300}{0313}
\DeclareEncodedCompositeAccents{\LastDeclaredEncoding}{\accpsiliperispomeni}{0342}{0313}

UPPERCASE

The common Greek font encoding definitions in greek-fontenc.def extend the uclclist with Greek LICR macros. Here, we add EU1 specific “hiatus” handling.

Mark hiatus

Tonos and dasia mark a hiatus if placed on the first vowel of a diphthong (ΑΙ, ΑΥ, ΕΙ). A dialytika must be placed on the second vowel if they are dropped (άυλος → ΑΫΛΟΣ, μάινα → ΜΑΪΝΑ, κέικ → ΚΕΪΚ, ἀυπνία → ΑΫΠΝΙΑ).

Look ahead and place a diaeresis on Ι or Υ (copied from lgrenc.def and changed Latin transcription to Unicode literals):

  \LGR@ifnextchar{Ι}{A\"}{%
