Abstract
The LGR font encoding is the de-facto standard for Greek typesetting with LaTeX. This file provides a comprehensive set of macros to typeset Greek with LGR encoded fonts. It works for both, monotonic and polytonic Greek, independent of the babel package.

Load this file by calling fontenc with the LGR option or indirectly via the babel, textalpha or alphabeta packages.
Select font encodings T1 (as default) and LGR (for Greek):
\usepackage[LGR,T1]{fontenc}
Note
The use of \@ifundefined has the side-effect that the tested macro becomes defined and set to \relax (polluting the namespace and interfering with tests via eTeX’s \ifdefined). However, in this case no harm is done as the macro is defined by the identification below anyway.

Declare the LGR font encoding and base substitutions:
\DeclareFontEncoding{LGR}{}{}
\DeclareFontSubstitution{LGR}{cmr}{m}{n}
\DeclareErrorFont{LGR}{cmr}{m}{n}{10}
Greek letters are accessible by the Latin transcription, but the mapping is specific to the LGR font encoding.
The LICR macros provide a way to access the symbols independent of the specific font encoding, in any font encoding supporting Greek. An alternative Greek font encodings is LGI (ibycus). Greek script is also supported by the Unicode-based font encodings PU (PDF Unicode used by hyperref for PDF metadata), TU, EU1 (XeTeX) and EU2 (LuaTeX). The textalpha package makes these macros available independent of the current font encoding.

Mathematical notation distinguishes variant shapes for pi, phi, rho, theta (small and capital), beta, and kappa (characters for the latter three symbols are not included in TeX’s math fonts). These variations have no syntactic meaning in Greek text and are not given code-points in the LGR encoding. Greek text fonts use the shape variants interchangeabely.
However, as Unicode defines separate code points for the symbol variants, we provide fallback LICR macros with detailed error reporting:
\providecommand*{\LGR@TextSymbolUnavailable}[1]{%
\PackageError{greek-fontenc}{character \string#1 not available \MessageBreak
in 8-bit TeX}
{Use XeTeX/LuaTeX if you need to distinguish the symbol from the letter.\MessageBreak

T3 (tipa):
\DeclareTextSymbol{\textschwa}{LGR}{26} % ə
T3 also defines some greek letters as well as Latin characters with Greek names:
According to the Unicode standard, the following IPA characters are identic to the Greek letters:
03B2 greek small letter beta
03B8 greek small letter theta
03BB greek small letter lamda
03C7 greek small letter chi
The following characters in the IPA block refer to Greek letters:
0251 LATIN SMALL LETTER ALPHA → greek small letter alpha - 03B1
025B LATIN SMALL LETTER OPEN E = epsilon → greek small letter epsilon - 03B5
0263 LATIN SMALL LETTER GAMMA → greek small letter gamma - 03B3
0269 LATIN SMALL LETTER IOTA → greek small letter iota - 03B9
0278 LATIN SMALL LETTER PHI → greek small letter phi - 03C6
028A LATIN SMALL LETTER UPSILON → greek small letter upsilon - 03C5
tipa uses the macro names \textepsilon, \textgamma, \textiota, \textphi, and \textupsilon for the Latin characters. This is no problem with 8-bit fonts (set the font encoding to T3 vs. LGR to disambiguate), but leads to ambiguity with Unicode fonts. xunicode uses the gr infix and alias names to disambiguate:
03B3 \textgrgamma
03B9 \textgriota
03C6 \textgrphi (see x0278 )
but not for epsilon and upsilon (03C2 \textgrsigma is the final sigma).
It also assigns alias names to the Latin counterparts, however not on a systematical basis:
0194 \textGammaafrican
0196 \textIotaafrican
0251 \textscripta
025B \texteopen
0263 \textbabygamma, \textgammalatinsmall
0269 \textiotalatin
028A \textscupsilon % TIPA-U
The characters at position 16 and 17 are used in the \nexus macro of the teubner package to form an extensible, hat-like bracket. In CB.enc, they are mapped to
16–MODIFIER LETTER LOW ACUTE ACCENT 17–MODIFIER LETTER LOW GRAVE ACCENT
but according to the documentation of Werner Lemberg’s babel patch, they rather represent the left and right part of U+23E0 TOP TORTOISE SHELL BRACKET.
Babel’s lgrenc.def has some definitions to prevent surprises with macros that expect a Latin script. These definitions are problematic in a font-encoding definition file as they require \textlatin which is defined in babel.def. They were moved to greek.ldf.
This section defines named macros for Greek diacritics and standard symbol macros as alias for simple diacritics. Convenient input conventions for composite diacritics are defined as composite definitions.
Advantages:
input convention similar to LGR input encodings (just prepend a \).
Access pre-composed characters without resorting to the ligature mechanism (allows proper kerning, cf. teubner-doc).
Named macros can be used to ensure a font encoding supporting Greek is used. However, substitution with pre-composed characters works only for the active font encoding (cf. textalpha). Named accent macros can also 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 (cf. UPPERCASE below) and for composite diacritics.
Definitions are based on the teubner package by Claudio Beccari, the ucs package, and the babel patch by Werner Lemberg. Names are derived from the Unicode name with the prefix “acc” (cf. How to name accent macros? in the README) reducing the probability of incompatibilities compared to the two-letter teubner diacritic macros or the “text” prefix used by ucs.
Simple Greek diacritics:
\DeclareTextAccent{\accdialytika}{LGR}{34} % διαλυτικά (diaeresis/trema)
\DeclareTextAccent{\acctonos}{LGR}{39} % τόνος/ὀξεῖα tonos/oxia (acute)
\DeclareTextAccent{\accdasia}{LGR}{60} % δασεῖα spiritus asper (rough breathing)
\DeclareTextAccent{\accpsili}{LGR}{62} % ψιλή spiritus lenis (smooth breathing)
\DeclareTextAccent{\accvaria}{LGR}{96} % βαρεῖα (grave)
\DeclareTextAccent{\accperispomeni}{LGR}{126} % περισπωμένη (circonflex/tilde)
The sub-iota is input after the base character. In LGR fonts, ligatures are defined for pre-composed characters, the postfix ligature does not interfere with kerning:
\DeclareTextSymbol{\prosgegrammeni}{LGR}{8} % ι "capital" sub-iota
\DeclareTextSymbol{\ypogegrammeni}{LGR}{124} % ͺ "small" sub-iota
Composite diacritics:
% Teubner name
\DeclareTextAccent{\accdialytikaperispomeni}{LGR}{32} % Cd
\DeclareTextAccent{\accdialytikatonos}{LGR}{35} % Ad
\DeclareTextAccent{\accdialytikavaria}{LGR}{36} % Gd
\DeclareTextAccent{\accdasiaperispomeni}{LGR}{64} % Cr
\DeclareTextAccent{\accdasiavaria}{LGR}{67} % Gr
\DeclareTextAccent{\accdasiaoxia}{LGR}{86} % Ar
\DeclareTextAccent{\accpsiliperispomeni}{LGR}{92} % Cs
\DeclareTextAccent{\accpsilioxia}{LGR}{94} % As
\DeclareTextAccent{\accpsilivaria}{LGR}{95} % Gs
For classical Greek and linguistics, the LGR font encoding contains a number of additional diacritic symbols:
\DeclareTextAccent{\accinvertedbrevebelow}{LGR}{1} % INVERTED BREVE BELOW
\DeclareTextAccent{\textsubarch}{LGR}{1} % (tipa)
\DeclareTextAccent{\accbrevebelow}{LGR}{20} % BREVE BELOW
\DeclareTextAccent{\u}{LGR}{30} % BREVE (Greek vrachy)
\DeclareTextAccent{\=}{LGR}{31} % MACRON
The standard symbol macros are exclusively used for Greek diacritics in LGR:
\DeclareTextCommand{\"}{LGR}{\accdialytika}
\DeclareTextCommand{\'}{LGR}{\acctonos}
\DeclareTextCommand{\`}{LGR}{\accvaria}
\DeclareTextCommand{\~}{LGR}{\accperispomeni}
The file greek-fontenc.def contains font encoding definitions that are shared by font encodings providing Greek characters:
\input{greek-fontenc.def}
Composite accents can be input as sequence of simple diacritics (in arbitrary order) via named macro, symbol macro and “transcription characters”, e.g. \accdialytica\accvaria\textalpha, \"\'\textalpha, \"'\textalpha, or \'"\textalpha.
The actual declarations are part of the common Greek font encoding definitions.

In Greek, diacritics are omitted in all-uppercase words, but kept as part of an uppercase initial (written before rather than above the letter).
The diaytika should also always be used in all-uppercase words (even in cases where they are not needed when writing in lowercase)
In Title Case, place diacritics before instead of above the base character:

The common Greek font encoding definitions in greek-fontenc.def extend the uclclist with Greek LICR macros. Here, we add LGR specific “hiatus” handling.
Composite commands for Latin transliteration:
\DeclareTextCompositeCommand{\LGR@hiatus}{LGR}{A}{\LGR@A@hiatus}
\DeclareTextCompositeCommand{\LGR@hiatus}{LGR}{E}{\LGR@E@hiatus}
TODO: What does the LGR@hiatus command “see” if a Unicode literal follows?
% \DeclareTextCompositeCommand{\LGR@hiatus}{LGR}{\symbol{"ce}}{bluff}
% \DeclareTextCompositeCommand{\LGR@hiatus}{LGR}{"cf}{blaff}
% \DeclareTextCompositeCommand{\LGR@hiatus}{LGR}{ι}{blaff}Look ahead and place a diaeresis on Ι or Υ:
\DeclareTextCommand{\LGR@A@hiatus}{LGR}{%
\LGR@ifnextchar{I}{A\"}{%
\LGR@ifnextchar{U}{A\"}{%
\LGR@ifnextchar{\textIota}{A\"}{%
\LGR@ifnextchar{\textUpsilon}{A\"}{A}%
}%
}%
}%
}
\DeclareTextCommand{\LGR@E@hiatus}{LGR}{%
\LGR@ifnextchar{I}{E\"}{%
\LGR@ifnextchar{U}{E\"}{%
\LGR@ifnextchar{\textIota}{E\"}{%
\LGR@ifnextchar{\textUpsilon}{E\"}{E}%
}%
}%
}%
}
Unfortunately, the lookahead breaks kerning.
Alternatives tried:
CompositeCommands fail at the end of a macro, e.g. \emph{\'a}
\DeclareTextCommand{\LGR@A@hiatus}{LGR}{A}
\DeclareTextCommand{\LGR@E@hiatus}{LGR}{E}
\DeclareTextCompositeCommand{\LGR@A@hiatus}{LGR}{}{A}
\DeclareTextCompositeCommand{\LGR@A@hiatus}{LGR}{I}{A\"I}
\DeclareTextCompositeCommand{\LGR@A@hiatus}{LGR}{U}{A\"U}The glyph No 12 is a special “Upcase Alpha” that in ligature with Y and I adds a diaresis to them. However, it seems that it has only kerning definitions for I and Y (as it is not intended for direct use)
\DeclareTextComposite{\LGR@hiatus}{LGR}{A}{12}No such glyph exists for E but this is no problem as E does not require kerning anyway.
