Abstract

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

Motivation

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

Implementation

Identification

\ProvidesFile{tuenc-greek.def}
  [2023-09-12 2.5 Greek LICRs for XeTeX and LuaTeX]

Auxiliary command (modeled after definitions in tuenc.def):

\providecommand*{\DeclareUnicodeCompositeCommand}[2]{%
  \DeclareTextCompositeCommand{#1}{\UnicodeEncodingName}{#2}
}

Greek Diacritics

Define “named macros” for simple and combined diacritics.

  • Named accent macros can be used instead of the \@tabacckludge by to-LaTeX converters to ensure working also inside the tabbing environment.

  • Named macros are required for upcasing according to Greek typesetting conventions and in the definition of composite commands.

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) COMBINING COMMA ABOVE
\DeclareUnicodeAccent{\accdasia}\UnicodeEncodingName{"0314} % δασεῖα spiritus asper (rough breathing)

Mute iota:

The following two macros are both used after the base character: \prosgegrammeni (adscript iota) is a spacing character (see below), \ypogegrammeni (subscript iota) is a combining character (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\relax\char"0301\relax}

Perispomeni and tilde accent

XeTeX normalizes letters followed by combining characters to a pre-composed character, if there is an equivalent pre-composed character (Unicode normalization NFC). With LuaTeX NFC is provided by the emph{Harfbuzz} renderer (select with the [Renderer=Harfbuzz] option of the fontspec font selection commands or the uninormalize package.

The \accperispomeni macro expands to COMBINING GREEK PERISPOMENI while the standard short accent macro \~ uses the COMBINING TILDE. Only <Greek letter> + COMBINING GREEK PERISPOMENI is considered equivalent to the pre-composed <Greek letter> WITH PERISPOMENI. Therefore, we define composite definitions for \~:

\DeclareUnicodeComposite{\~}{\textalpha  }{"1FB6} % ᾶ
\DeclareUnicodeComposite{\~}{\texteta    }{"1FC6} % ῆ
\DeclareUnicodeComposite{\~}{\textiota   }{"1FD6} % ῖ
\DeclareUnicodeComposite{\~}{\textupsilon}{"1FE6} % ῦ
\DeclareUnicodeComposite{\~}{\textomega  }{"1FF6} % ῶ

There are no pre-composed capital letters with perispomeni (the perispomeni is not used on initial letters and normally dropped in UPPERCASE). However, it is kept with the pre-2022 \MakeUppercase and in documents that don’t load babel-greek (or an old babel-greek or use the modifier local-MakeUppercase-fixes):

\DeclareUnicodeCompositeCommand{\~}{\textAlpha  }{\accperispomeni\textAlpha}
\DeclareUnicodeCompositeCommand{\~}{\textEta    }{\accperispomeni\textEta}
\DeclareUnicodeCompositeCommand{\~}{\textIota   }{\accperispomeni\textIota}
\DeclareUnicodeCompositeCommand{\~}{\textUpsilon}{\accperispomeni\textUpsilon}
\DeclareUnicodeCompositeCommand{\~}{\textOmega  }{\accperispomeni\textOmega}

Using literal Unicode chars leads to errors in LuaTeX’s 8-bit compatibility mode. OTOH, composite definitions do a literal check, so we cannot use a replacement:

\@ifl@aded{sty}{luainputenc}{}{% else
  \DeclareUnicodeComposite{\~}{α}{"1FB6} % ᾶ
  \DeclareUnicodeComposite{\~}{η}{"1FC6} % ῆ
  \DeclareUnicodeComposite{\~}{ι}{"1FD6} % ῖ

  \DeclareUnicodeComposite{\~}{ω}{"1FF6} % ῶ

  \DeclareUnicodeCompositeCommand{\~}{Α}{\accperispomeni Α}

UPPERCASE

Greek letters drop diacritics (eccept dialytika and sub-iota) in UPPERCASE.

Babel-Greek introduces macros for “capital accents” in release 1.13.3. Here, we add definitions to drop diacritics in uppercase:

\DeclareUnicodeCompositeCommand{\accACUTE}{\textAlpha  }{\LGR@A@hiatus}
\DeclareUnicodeCompositeCommand{\accACUTE}{\textEpsilon}{\LGR@E@hiatus}
\DeclareUnicodeComposite{\accACUTE}{\textEta    }{"0397} % Η
\DeclareUnicodeComposite{\accACUTE}{\textIota   }{"0399} % Ι
\DeclareUnicodeComposite{\accACUTE}{\textOmicron}{"039F} % Ο
\DeclareUnicodeComposite{\accACUTE}{\textUpsilon}{"03A5} % Υ
\DeclareUnicodeComposite{\accACUTE}{\textOmega  }{"03A9} % Ω

\DeclareUnicodeComposite{\accGRAVE}{\textAlpha  }{"0391} % Α
\DeclareUnicodeComposite{\accGRAVE}{\textEpsilon}{"0395} % Ε
\DeclareUnicodeComposite{\accGRAVE}{\textEta    }{"0397} % Η
\DeclareUnicodeComposite{\accGRAVE}{\textIota   }{"0399} % Ι
\DeclareUnicodeComposite{\accGRAVE}{\textOmicron}{"039F} % Ο
\DeclareUnicodeComposite{\accGRAVE}{\textUpsilon}{"03A5} % Υ
\DeclareUnicodeComposite{\accGRAVE}{\textOmega  }{"03A9} % Ω

\DeclareUnicodeComposite{\accTILDE}{\textAlpha  }{"0391} % Α
\DeclareUnicodeComposite{\accTILDE}{\textEta    }{"0397} % Η
\DeclareUnicodeComposite{\accTILDE}{\textIota   }{"0399} % Ι
\DeclareUnicodeComposite{\accTILDE}{\textUpsilon}{"03A5} % Υ
\DeclareUnicodeComposite{\accTILDE}{\textOmega  }{"03A9} % Ω

Repeat with literal Unicode as base character (fails in LuaTeX’s 8-bit compatibility mode):

\@ifl@aded{sty}{luainputenc}{}{% else
  \DeclareUnicodeCompositeCommand{\accACUTE}{Α}{\LGR@A@hiatus}
  \DeclareUnicodeCompositeCommand{\accACUTE}{Ε}{\LGR@E@hiatus}

The new (2022) implementation of \MakeUppercase drops accents from literal Unicode input (if the text language is set to Greek with Babel).

With the old \MakeUppercase implementation, we can fix this using \lccode and \uccode corrections from the xgreek package by Apostolos Syropoulos:

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 transliteration 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}%
      }%
    }%
  }%
}
