[2012/07/03 v0.2 macros for Greek letters in text]
This package is part of the lgrx bundle.
Abstract
Provide a set of \text* macros for Greek letters outside math.
Note
The package was renamed from textgreek to textalpha to prevent confusion with the textgreek package by Leonard Michlmayr.

support for compound Unicode definitions outside LGR |
By default, macros for Greek letters
are only valid in mathematical mode,
do not change shape (default shape is italic).
In Greek text fonts with the LGR font encoding, letters are accessible by a Latin transcription.
This package provides a set of macros that can be used to access Greek symbols from a font in LGR encoding (e.g. the CB fonts) without the need for an explicite font-encoding switch.
The macro names follow the established scheme to prepend \text* to the Adobe glyph name (if it exists) or the corresponding math-macro, so \textalpha -- \textOmega prints α – Ω.
In combination with the \text macro from amsmath, this can be used to get matching upright and bold upright Greek symbols in math as well.
In combination with \usepackage[utf8]{inputenc} and the accompanying lgrenc.dfu file, Unicode input of Greek characters is supported.
This is done using NFSS default definitions as explained in the fntguide (section 5.3).
While the macros work reasonably well for single letters, the automatic font-encoding switches behind the doors interferes with the kerning between the letters and replacement of accent+character with a pre-composed character.
Therefore, Greek text should be written with the help of babel, setting the language to either greek or polutonikogreek or wrapped in the provided \TextGreek macro.
This package requires the extended font encoding definitions
\input{lgrxenc.def}
The \TextGreek command can be used to ensure that its argument is set in a font encoding with support for Greek. We define LGR as default encoding for Greek text:
\DeclareTextCommandDefault{\TextGreek}[1]{{\fontencoding{LGR}\selectfont #1}}
Font encodings supporting Greek script (e.g. LGI) may declare a specific text command that passes the argument unchanged. This way, kerning and selection of precomposed glyphs work also for cases like \TextGreek{\'A}U.
Define the text* marcos as default for all font encodings:
