Abstract

This package provides input encoding definition files for the Greek script for use with inputenc.

## Files

Input encoding definitions:

lgrenc.dfu: Greek UTF-8 support with inputenc

  Input encoding file for UTF-8 comprising Greek letters and other symbols present in the LGR encoding.

iso-8859-7.def

  Greek input encoding file for ISO 8859-7 by Apostolos Syropoulos.

macgreek.def

  Greek input encoding file for Macintosh (ELOT 823) by Dimitrios Filippou.

  This file translates to a Latin transliteration particular to the LGR font encoding. Drawbacks include: Latin characters in PDF strings (hyperref bookmarks and TOC sidebar, cf. Greek and hyperref), no kerning between accented characters.

Test examples and output:

greek-utf8.tex

  greek-utf8.pdf (comprehensive example)

inputenc-iso-8859-7.tex

  inputenc-iso-8859-7.pdf (basic test)

HTML documentation was generated from the literate source with PyLit and from reStructuredText with Docutils.

## Installation

If possible, get this package from your distribution using its installation manager.

Otherwise, make sure LaTeX can find the files ending in .def and .dfu:

- Download and unpack the package or just the required file(s).

- Copy, move, or link the files to a suitable place in the TeX Directory Structure (TDS) and run texhash, or place them in the current working directory (e.g. for testing).

## Usage

The April 2018 LaTeX release changed the default encoding for 8-bit LaTeX from 7-bit ASCII to utf-8. Hence, the \usepackage[<encoding>]{inputenc} command is only required with the legacy 8-bit encodings. [ltnews28]

However, literal Unicode characters are only set up, if they are supported by a declared font encoding. This package works with the LGR font encoding (requires greek-fontenc). Specify the LGR font encoding with any combination of fontenc, the “greek” option for Babel, or the textalpha or alphabeta packages, e.g.

    \usepackage[LGR,T1]{fontenc}

or

    \usepackage{textalpha}
    \usepackage[greek,english]{babel}

See greek-utf8.tex for an example.

By default, text containing Greek Unicode characters must be marked up with a command that selects a font encoding supporting the Greek script, e.g. by setting the Babel language to greek or polutonikogreek

    Athens (Greek: \foreignlanguage{greek}{Αθήνα};
            Ancient Greek: \foreignlanguage{greek}{Ἀθῆναι})
    is the capital of Greece.

This is a generic feature of 8-bit LaTeX – an equivalent restriction holds for the Cyrillic script.

With the textalpha or alphabeta packages (provided as part of greek-fontenc), Greek Unicode literals can be used without special markup also in non-Greek documents (with some limitations).

### Warning

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 usage.pdf for a description of this Latin-Greek transliteration.)

This means you need an explicit 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 \ensureascii{k}Ω}

Special care is also required with the question mark characters:

- The Unicode standard says character 003B SEMICOLON (and not 037E) is the preferred character for Greek question mark.

- The LGR font encoding maps the semicolon to a middle dot (ano teleia), while the Latin question mark is mapped to the erotimatiko.

As a result, only the deprecated character 037E GREEK QUESTION MARK works with both, Xe/LuaTeX and 8-bit TeX.

Alternatively, the textalpha and alphabeta packages from greek-fontenc can be loaded with the “keep-semicolon” option.
