[2020/10/13 2.0 Greek LICRs for XeTeX and LuaTeX]

Abstract

Support for Greek LICR macros and upcasing of text with XeTeX and LuaTeX. Extends tuenc.def. Used by babel-greek and textalpha.

History:

0.1

2013-07-16

initial version

0.1.1

2013-07-18

bugfix: wrong breathings psilioxia -> dasiaoxia

0.1.2

2013-07-19 ..

bugfix: Disable composite defs starting with char macro, fix “hiatus” handling.

0.1.3

2013-07-24

fix “input” path.

0.1.4

2013-10-01 ..

remove clashing defs for legacy characters with oxia, fix upcasing of \finalsigma.

0.11.1

2013-12-01

fix identification.

0.11.2

2014-09-08

\textKoppa macro

(Capital Koppa is not defined in LGR but Unicode).

0.12

2014-12-12

Remove symbol macros for breathing accents.

0.13

2015-08-07

\lccode/\uccode corrections from xgreek.

LICR macros for symbol variants.

0.13.3

2018-01-06

Documentation update.

0.14

2020-02-28

Rename to tuenc-greek.def. Use \UTFencname.

1.0

2020-09-25

New package version. No changes in this file.

2.0

2020-10-13

Move common alias definitions to greek-fontenc.def.

New compatiblity definitions.

Use \UnicodeEncodingName instead of \UTFencname.

Make the file encoding-independent (required for input in other encodings with luainputenc).

Contents

Motivation

LICR macro definitions for the Greek script are missing in tuenc.def (as well as the predecessors xunicode, euenc).

This file defines LaTeX Internal Character Representaction (LICR) macros for Greek letters and symbols. It works independed of xunicode using the standard commands for LaTeX2e font selection.

Requirements

Requires XeTeX or LuaTeX (usually with fontspec), the LaTeX base file tuenc.def that sets up the font encoding TU, and a font with Greek characters.

See test-tuenc-greek.tex and test-tuenc-greek.pdf for setup and usage examples.

Greek Diacritics

Define “named macros” for simple and combined diacritics.

Greek alias names for standard accents:

\DeclareUnicodeAccent{\accvaria}    \UnicodeEncodingName{"0300}
\DeclareUnicodeAccent{\acctonos}    \UnicodeEncodingName{"0301}
\DeclareUnicodeAccent{\accdialytika}\UnicodeEncodingName{"0308}

The combining perispomeni character is normalized with Greek base letters, while the (standard) combining tilde is not:

\DeclareUnicodeAccent{\accperispomeni}\UnicodeEncodingName{"0342} % COMBINING GREEK PERISPOMENI

Breathings:

\accpsili = \acckoronis but the COMBINING GREEK KORONIS is a legacy character, discarded in favour of COMBINING COMMA ABOVE.

\DeclareUnicodeAccent{\accpsili}\UnicodeEncodingName{"0313} % ψιλή spiritus lenis (smooth breathing)
\DeclareUnicodeAccent{\accdasia}\UnicodeEncodingName{"0314} % δασεῖα spiritus asper (rough breathing)

Sub-iotas:

\prosgegrammeni is a standard character (see below). \ypogegrammeni is a postfix accent (ligature in LGR)

\DeclareTextSymbol{\ypogegrammeni}{\UnicodeEncodingName}{0837} % COMBINING GREEK YPOGEGRAMMENI

Combined diacritics:

\DeclareUnicodeAccent does not work with more than one argument:

% The COMBINING DIALYTIKA TONOS is discarded and not well supported by fonts:
\DeclareTextCommand{\accdialytikatonos}{\UnicodeEncodingName}[1]{#1\char"0308\char"0301}
\DeclareTextCommand{\accdialytikavaria}{\UnicodeEncodingName}[1]{#1\char"0308\char"0300}
\DeclareTextCommand{\accdialytikaperispomeni}{\UnicodeEncodingName}[1]{#1\char"0342\char"0308}

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

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

We skip definitions for characters “… WITH OXIA”, because they would overwrite the definitions for “… WITH TONOS” in the Greek and Coptic block.

uclclist

The common Greek font encoding definitions in greek-fontenc.def extend the uclclist with Greek LICR macros. Here, we add Unicode-specific “hiatus” handling (copied from lgrenc.def and changed Latin transcription to Unicode literals).

The hiatus definition modifications:

\DeclareTextCommand{\LGR@A@hiatus}{\UnicodeEncodingName}{%
  \LGR@ifnextchar{Ι}{\textAlpha\"}{%
    \LGR@ifnextchar{Υ}{\textAlpha\"}{%
      \LGR@ifnextchar{\textIota}{\textAlpha\"}{%
        \LGR@ifnextchar{\textUpsilon}{\textAlpha\"}{\textAlpha}%
      }%
    }%
  }%
}
\DeclareTextCommand{\LGR@E@hiatus}{\UnicodeEncodingName}{%
  \LGR@ifnextchar{Ι}{\textEpsilon\"}{%
    \LGR@ifnextchar{Υ}{\textEpsilon\"}{%
      \LGR@ifnextchar{\textIota}{\textEpsilon\"}{%
        \LGR@ifnextchar{\textUpsilon}{\textEpsilon\"}{\textEpsilon}%
      }%
    }%
  }%
}
