Terminology is confusing since the +lining figures (which are now the default) are a relatively recent +development (19th century) and before they arrived, oldstyle figures +were the norm, even when setting mathematics. (An example is Thomas +Harriot’s <em>Artis Analyticae Praxis</em> published in 1631). In a +typical old style 3, 4, 5, 7 and 9 have descenders and 6 and 8 ascend +above the x-height; sometimes 2 will also ascend (this last seems to +be a variation associated with French typography). +<p/>LaTeX provides a command <code>\</code><code>oldstylenums{</code><em>digits</em><code>}</code>, which +by default uses an old-style set embedded in Knuth’s ‘math italic’ +font. The command isn’t sensitive to the font style of surrounding +text: the glyphs are only available to match the normal medium weight +Computer Modern Roman fonts. +<p/>The <i>textcomp</i> package changes <code>\</code><code>oldstylenums</code> to use the +glyphs in the Text Companion fonts (LaTeX TS1 encoding) when +in text mode, and also makes them available using the macros of the +form <code>\</code><code>text<number>oldstyle</code>, e.g., <code>\</code><code>textzerooldstyle</code>. +(Of course, not all font families can provide this facility.) +<p/>Some font packages (e.g., <i>mathpazo</i>) make old-style figures +available and provide explicit support for making them the default: +<code>\</code><code>usepackage[osf]{mathpazo}</code> selects a form where digits are +always old-style in text. The <i>fontinst</i> package will +automatically generate “old-style versions” of commercial Adobe Type +1 font families for which “expert” sets are available. +<p/>It’s also possible to make virtual fonts, that offer old-style digits, +from existing font packages. The <i>cmolddig</i> bundle provides +a such a virtual version of Knuth’s originals, and the <i>eco</i> +or <i>hfoldsty</i> bundles both provide versions of the EC +fonts. The <i>lm</i> family offers old-style figures to OpenType +users (see below), but we have no stable mapping for <i>lm</i> +with old-style digits from the Adobe Type 1 versions of the fonts. +<p/>Originally, oldstyle figures were only to be found the expert sets of +commercial fonts, but now they are increasingly widely available. An +example is Matthew Carter’s Georgia font, which has old-style figures +as its normal form (the font was created for inclusion with certain +Microsoft products and is intended for on-screen viewing). +<p/>OpenType fonts have a pair of axes for number variations — +proportional/tabular and lining/oldstyle selections are commonly +available. “Full feature access” to OpenType fonts, making such +options available to the (La)TeX user, is already supported by +<a href="FAQ-xetex.html">XeTeX</a> using, for example, the <i>fontspec</i> +package. Similar support is also in the works for +<a href="FAQ-luatex.html">LuaTeX</a>. +<dl> +<dt><tt><i>cmolddig fonts</i></tt><dd><a href="http://www.tex.ac.uk/www.tex.ac.uk tex-archive/fonts/cmolddig.zip">fonts/cmolddig</a> (or <a href="http://www.tex.ac.uk/www.tex.ac.uk tex-archive/fonts/cmolddig/">browse the directory</a>) +<dt><tt><i>eco fonts</i></tt><dd><a href="http://www.tex.ac.uk/www.tex.ac.uk tex-archive/fonts/eco.zip">fonts/eco</a> (or <a href="http://www.tex.ac.uk/www.tex.ac.uk tex-archive/fonts/eco/">browse the directory</a>) +<dt><tt><i>fontinst</i></tt><dd><a href="http://www.tex.ac.uk/www.tex.ac.uk tex-archive/fonts/utilities/fontinst.zip">fonts/utilities/fontinst</a> (or <a href="http://www.tex.ac.uk/www.tex.ac.uk tex-archive/fonts/utilities/fontinst/">browse the directory</a>) +<dt><tt><i>fontspec.sty</i></tt><dd><a href="http://www.tex.ac.uk/www.tex.ac.uk tex-archive/macros/xetex/latex/fontspec.zip">macros/xetex/latex/fontspec</a> (or <a href="http://www.tex.ac.uk/www.tex.ac.uk tex-archive/macros/xetex/latex/fontspec/">browse the directory</a>) +<dt><tt><i>mathpazo fonts</i></tt><dd><a href="http://www.tex.ac.uk/www.tex.ac.uk tex-archive/fonts/mathpazo.zip">fonts/mathpazo</a> (or <a href="http://www.tex.ac.uk/www.tex.ac.uk tex-archive/fonts/mathpazo/">browse the directory</a>) +</dl> +<p/> +<p/><p/><p/><p/><p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=osf">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=osf</a> +</body> |
