+<h3>Using &ldquo;old-style&rdquo; figures</h3>
+<p/>These numbers are also called medieval or lowercase figures and their
+use is mostly font-specific. 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&rsquo;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&rsquo;s &lsquo;math italic&rsquo;
+font. The command isn&rsquo;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&lt;number&gt;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 &ldquo;old-style versions&rdquo; of commercial Adobe Type
+1 font families for which &ldquo;expert&rdquo; sets are available.
+<p/>It&rsquo;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&rsquo;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&rsquo;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 &mdash;
+proportional/tabular and lining/oldstyle selections are commonly
+available. &ldquo;Full feature access&rdquo; 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>.
