85     \section{Introduction}
87     This document explains how to use the \TeX/\LaTeX/\ConTeXt\ support in
88     the present package for the Gentium font collection developed by \sil.
89     This package includes fonts in PostScript Type~1 format converted from
90     the original TrueType files released by \sil\ (using the FontForge
91     routines found in this package). These Type~1 fonts use the name
92     `Gentium' by permission of \sil\ to the \TeX\ Users Group. Therefore
93     the name of this \TeX\ package, by request of \sil, is
94     \pkgname{gentium-tug}. Its home page is \url{http://tug.org/gentium}.
96     Further information about the fonts themselves can be found in the
97     included documentation and at \url{http://scripts.sil.org/gentium}. The
98     fonts are released under the \textsc{sil} Open Font License. For
99     details, see \url{ofl.txt} and \url{ofl-faq.txt}. (In the event of
100     releasing modified versions of the fonts, either TrueType or Type~1,
101     it's required to use a name that doesn't include ``Gentium'', per the
102     \textsc{ofl}.)
104     This \TeX/\LaTeX/\ConTeXt\ support package consists of metrics, map
105     files, style files, documentation, and so on. These files are released
106     under the Expat license. The text for both licenses is included at the
107     end of this document, and in files in the distribution.
109     If you have the package installed and just want to know how to use
110     Gentium in your \TeX\ documents, feel free to skip to
111     section~\ref{sec:latex-package} (\LaTeX\ usage) or
112     section~\ref{sec:context-package} (\ConTeXt\ usage).
114     Please report any problems (contact info on the web page). If you can
115     also send a fix, so much the better.
118     \section{Gentium collection background}
120     This package uses the original fonts GentiumPlus to make the regular and
121     italic styles and GentiumBasic to make the bold and bold italic styles,
122     and combines them into one \TeX-world family.
124     GentiumPlus is a serif family designed to support a wide range of Latin,
125     Greek and Cyrillic characters. It currently includes just the regular
126     and italic style, as well as smallcaps.
128     GentiumBasic has just the Latin characters and it even lacks some Latin
129     characters found in GentiumPlus. Therefore, the bold and bold italic
130     styles of this package support fewer languages than the regular and
131     italic styles (e.g.\ Czech and Slovak are not fully
132     supported). Moreover, GentiumBasic has no smallcaps and no kerning
133     pairs. When and if \sil\ releases bold and bold italic GentiumPlus
134     fonts, we will switch to those, of course.
136     This package does not use the Berry fontname scheme, but longer names
137     similar to those of Latin Modern, etc. One disadvantage of this choice
138     is that you cannot use the additional font selection commands provided
139     by the package \pkgname{nfssext-cfr}.
142     \section{Installation}
144     If you are using a reasonably recent \MiKTeX\ or \TeXLive\ or distro
145     installation it should be enough to install the \pkgname{gentium-tug}
146     package (if it's not already present).
148     Otherwise, or if you want to install the font manually, you will in
149     general need to perform these steps:
150     \begin{enumerate}
151     \item choose whether to install the font system-wide or in a personal
152     directory;
153     \item move or copy the package files to the appropriate location;
154     \item refresh the \TeX\ database;
155     \item incorporate the included map file fragments for the different
156     engines.
157     \end{enumerate}
159     However, that's all that it make sense to say here. It's beyond the
160     scope of this Gentium documentation to explain all the myriad ways in
161     which \TeX-world map files can be installed and used; there are
162     differences between \TeXLive\ and \MiKTeX, too.
164     Instead, we refer you to an explanation of the system-wide installation,
165     with information for both \MiKTeX\ and \TeXLive, at
166     \url{http://tug.org/fonts/fontinstall.html}. A corresponding
167     explanation for personal installation is at
168     \url{http://tug.org/fonts/fontinstall-personal.html}.
170     Those pages describe using \path{testfont.tex} for a basic test of the
171     font; a tfm file name to use with that is \url{ec-gentiumplus-regular}.
173     To further test your installation and that the package works on your
174     system, run \LaTeX\ on this \path{gentium.tex} source file. (You'll
175     need some commonly-available \LaTeX\ packages too, or comment them at.)
176     The console output and/or log should tell you whether any fonts were not
177     found. You can also compare your output with the original
178     \path{gentium.pdf}.
181     \section{Gentium \TeX\ support packages}\label{sec:support}
183     In short, for \LaTeX\ it suffices to include \verb|\usepackage{gentium}|
184     in your document preamble, and for \ConTeXtMKIV,
185     \verb|\setupbodyfont[gentium]|. Details follow.
187     The only prerequisite is that the \LaTeX\ package (\path{gentium.sty})
188     requires \pkgname{xkeyval}, which you almost certainly already have.
191     \subsection{Encodings}\label{sec:encs}
193     The package supports not only the most common Latin encodings such as
194     \textsc{ot1}, TeXnANSI/\textsc{ly1}, Cork/\textsc{ec}/\textsc{t1} and
195     Text Companion/\textsc{ts1} encodings, but also (in regular and italic)
196     other Latin, Greek and Cyrillic encodings. Most characters in the text
197     encodings and some of those in the Text Companion encoding are
198     available, including the~\texteuro. You can see the available encodings
199     in table~\ref{encodings}. The Greek encoding LGR is supported only in
200     \LaTeX, AGR only in \ConTeXt.
202     \begin{table}[h]
203     \centering
204     \begin{tabular}{lll}
205     \toprule
206     script & available encodings & styles \\
207     \midrule
208     Latin & OT1, T1, LY1, L7x, QX, T5, TS1 & regular, italic, bold,
209     bold italic \\
210     Cyrillic & T2A, T2B, T2C, X2 & regular, italic\\
211     Greek & LGR (\LaTeX), AGR (\ConTeXt) & regular, italic \\
212     \bottomrule
213     \end{tabular}
214     \caption{Available encodings in \pkgname{gentium-tug}.}
215     \label{encodings}
216     \end{table}
218     The regular and italic styles support all these Latin, Greek and Cyrillic
219     encodings. They support also small caps for the Latin and Cyrillic encodings,
220     but there are no small caps for Greek.
222     The bold and bold italic styles support only the Latin encodings and they
223     have no small caps.
225     Cork/T1 encoding lacks visible space, cwm (compound work mark),
226     SS and the character for composing permille sign.
228     Missing characters in bold styles for Latin encodings:
230     T1: Aogonek / aogonek, Eogonek / eogonek, Lcaron / lcaron,
231     Scedilla / scedilla, uni021A (Tcommaaccent) / uni021B (tcommaaccent),
232     dcaron, tcaron
234     L7x: Rcommaaccent, Gcommaaccent, Kcommaaccent, Lcommaaccent, Ncommaaccent,
235     Aogonek, Eogonek, Iogonek, Uogonek
237     QX: Aogonek, Eogonek, Iogonek, uni021A (Tcommaaccent)
240     \subsection{\LaTeX}
241     \label{sec:latex-package}
243     To use Gentium fonts in a \LaTeX\ document, add
244     \verb|\usepackage{gentium}| to your document preamble. This will set
245     the default serif/roman family to \fname{gentium}.
247     If you want to use Gentium together with another font (sans or
248     typewriter) with a different x-height, you should consider using the
249     option \verb|scaled|. This scales Gentium font and if you choose the
250     right scaling factor, you will get the same x-height of both fonts.
251     Here is an example of this option:
252     \begin{verbatim}
253     \usepackage[scaled=0.9]{gentium}
254     \end{verbatim}
257     \subsection{\ConTeXt}
258     \label{sec:context-package}
260     In \ConTeXtMKIV, to switch to the Gentium typeface you only need:
261     \begin{verbatim}
262     \setupbodyfont[gentium]
263     \end{verbatim}
265     In \ConTeXtMKII, before doing that you need either (for \pdfTeX):
266     \begin{verbatim}
267     \usetypescriptfile[type-gentium]
268     \usetypescript[gentium][ec] % or whatever encoding
269     \end{verbatim}
270     or (for \XeTeX):
271     \begin{verbatim}
272     \usetypescriptfile[type-gentium]
273     \usetypescript[gentium]
274     \end{verbatim}
277     \subsection{Changes in the Type~1 fonts vs.\ the TrueType originals}
279     The shapes of all characters in the Type~1 fonts are the same as in the
280     original TrueType fonts, except for the unavoidable changes are induced
281     by the format conversion (that is, the spline representations are
282     necessarily different).
284     However, a few small changes---hopefully improvements---were made to the
285     metrics of the GentiumPlus family (that is, regular and italic; bold and
286     bold italic are untouched). The Type~1 fonts are used to generate the
287     \TeX\ font metric files (tfm), so these changes propagate to the 8-bit
288     engines like \pdfTeX.
290     The first change concerns Greek. 8-bit Greek encodings (LGR and AGR) do
291     not use precomposed accented capital letters. These letters are composed
292     as a sequence of two glyphs: accent + capital letter. The problem is
293     that this sequence does not look like the precomposed letter---there is
294     often big space between the accent and the letter. Therefore, there are
295     some extra kerning pairs between accents and capital Greek
296     letters. These kerning pairs are created automatically (the script is
297     included in the sources) and the goal is to have the same relative
298     position between the accent and the letter as in the precomposed
299     letter. Thanks to these extra kerning pairs you should get better
300     results for 8-bit engines. These changes are irrelevant for Unicode
301     engines---they use the precomposed letters.
303     The second change is in the letters dcaron (ď) and lcaron
304     (ľ) that are used in the Czech and Slovak languages. (There was
305     no need to change tcaron (ť) and Lcaron (Ľ) with the same
306     accent.) There is no change of their shapes, and their advance widths
307     are also untouched---the change is to add several kerning pairs with
308     quite big negative values. Without these changes there was often a large
309     space between dcaron or lcaron and the following letter, so the changes
310     make the words containing these letters much more compact. You get these
311     changes automatically if you use 8-bit engines. If you use Unicode
312     engines with the original TrueType fonts, you get the original
313     metrics. However, you can tell the Unicode engines to use the Type~1
314     fonts (which append \verb|PS| to the family name) like this:
315     \begin{verbatim}
316     \usepackage{fontspec}
317     \setmainfont{GentiumPlusPS}
318     \end{verbatim}
319     Then you get the additional kern pairs for dcaron and lcaron. The
320     unfortunately disadvantage is that you cannot use small caps.
322     The last (similar) change is that additional kerning pairs were added to
323     the Type~1 fonts for accented Latin letters and small caps. The original
324     TrueType fonts have no such kerning pairs. As with the Czech/Slovak
325     changes, you get these changes automatically if you use 8-bit
326     engines. If you use Unicode engines with the original TrueType fonts,
327     you get the original metrics, but you can override as above (but since
328     you cannot use small caps with that method, the kerning pairs for small
329     caps become irrelevant).
332     \section{Known bugs}
334     There are problems in older versions of \pdfTeX\ with small caps when
335     using TrueType fonts. Especially the Latin encoding \textsc{t5} and all
336     Cyrillic encodings are unusable. You can use the Type~1 version of the
337     fonts or at least \pdfTeX\ version 1.40.13 to avoid these problems.
339     The Gentium fonts are a work in progress and as such they still miss
340     some features like kerning pairs for some letters. Currently, there are
341     no kerning pairs in the GentiumBasic family at all and the GentiumPlus
342     family has kerning pairs just for Latin letters without accents and for
343     Greek letters; there are no kerning pairs for small caps, accented Latin
344     letters or Cyrillic letters. The Type~1 fonts in this package have some
345     additional kerning pairs for accented Latin letters and for small
346     caps. Kerning pairs for Cyrillic are under consideration.
349     \section{License}
351     The fonts in this page, both the \sil\ originals and the derived Type~1
352     versions, are released under \textsc{ofl}. The \TeX\ support files
353     are licensed under the Expat License. Here are the full license texts.

524     % Some Clea's texts that might be used:
526     % The final option controls whether Latin Modern is used for sans and
527     % typewriter text. Because Computer Modern does not support the
528     % TeXnANSI/\textsc{ly1} encoding, you will likely get strange results
529     % unless you redefine \path{\sfdefault} and \path{\ttdefault}. Latin
530     % Modern is used because it is close to the default Computer Modern fonts
531     % and is widely available. If you would prefer that the package not
532     % redefine the default sans and typewriter families, use \verb|lm=false|
533     % when loading \pkgname{gentiumplus}. To explicitly request the default
534     % behaviour, which does redefine these families, use \verb|lm| or
535     % \verb|lm=true|.
537     % Loading \path{gentium.sty} does not affect the setup for
538     % mathematics.
