<title>UK TeX FAQ -- question label tradesyms</title>
</head><body>
<h3>How to get copyright, trademark, etc.</h3>
<p/>The &ldquo;
<a href="FAQ-symbols.html">Comprehensive symbol list</a>&rdquo;, lists
the symbol commands <code>\</code><code>textcopyright</code>,
<code>\</code><code>textregistered</code> and <code>\</code><code>texttrademark</code>, which are available in
TS1-encoded fonts, and which are enabled using the
<i>textcomp</i> package.
<p/>In fact, all three commands are enabled in default LaTeX, but the
glyphs you get aren&rsquo;t terribly beautiful.  In particular,
<code>\</code><code>textregistered</code> behaves oddly when included in bold text (for
example, in a section heading), since it is composed of a small-caps
letter, which typically degrades to a regular shape letter when asked
to set in a bold font.  This means that the glyph becomes a circled
&ldquo;r&rdquo;, whereas the proper symbol is a circled &ldquo;R&rdquo;.
<p/>This effect is of course avoided by use of <i>textcomp</i>.
<p/>Another problem arises if you want <code>\</code><code>textregistered</code> in a
superscript position (to look similar to <code>\</code><code>texttrademark</code>).
Using a maths-mode superscript to do this provokes lots of pointless
errors: you <em>must</em> use
<blockquote>
<pre>
\textsuperscript{\textregistered}
</pre>
</blockquote><p>
