I'm trying to include copyright © or registered ® symbols in my document. However they look terrible! As far as I can tell it is generating a small caps letter with a big circle around it (not even centered).

I have tried using \textregistered and also using [utf]{inputenc} and putting the symbol in directly... they both look the same. image

I am using [utopia]{mathdesign} for the fonts - perhaps this is something to do with it?

Use the textcomp package, which offers a \textregistered symbol (both serif and sans-serif), different to standard LaTeX which uses \textcircled.

\documentclass{article}
\usepackage{textcomp}
\begin{document}
\textregistered\textcopyright
\sffamily\textregistered\textcopyright
\end{document}

Output:

alt text

Here are the original LaTeX definitions from latex.ltx:

\DeclareTextCommandDefault{\textcopyright}{\textcircled{c}}
\DeclareTextCommandDefault{\textregistered}{\textcircled{%
      \check@mathfonts\fontsize\sf@size\z@\math@fontsfalse\selectfont R}}

If designed symbols like those of textcomp wouldn't fit to your text font, you could use \textcircled similarly to create a symbol with the used font together with some correction if necessary, with \raisebox etc.

For ConTeXt, use the \registered{} and \trademark{} macros.

How can a professional type-setting system like latex ship with a copyright symbol that by default is a "c" with a circle around? That sounds perverted :) –  Johannes Schaub - litb Aug 13 '10 at 18:54
    
Thanks -- this makes them look a lot better! (I also think it's strange that it doesn't use a glyph from a font but perhaps the older fonts don't have them) –  thrope Aug 13 '10 at 19:51

Many professional fonts have dedicated glyphs for the copyright and registered symbols, so if you are using a font like that you can simply use those glyphs. Some of the fonts available for free with TeX include these symbols - I checked Palantino, Utopia and Charter, they all have them. Most professional fonts I have seen have them.

The \copyright command defined in the TeXBook was a superposition of two characters, which is never going to look as good as a specifically-designed glyph. But copyright symbols are rare in mathematics publishing, apart from the copyright page, so it was probably a case of "good enough", particularly because of the font limitations of early TeX.

How do I use them? When I put unicode copyright symbol in it just did the same as \textcopyright –  thrope Aug 14 '10 at 14:52

In mathdesign (tested with utopia) and mathpazo, all I had to do is load the textcomp package, and the \copyright symbol automatically was replaced by the symbol from the font file. –  Carl Mummert Aug 14 '10 at 16:09
