[Tex/LaTex] Using “◌” in Latex – “Unicode char \u8:Γùî not set up for use with LaTeX”

symbolsunicode

How can I use the character ◌ (25CC): http://www.fileformat.info/info/unicode/char/25cc/index.htm ?

I am using MikTex (pdflatex) under Window; I am importing the following packages:

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

When pasting the character into my document, I receive the following error message:

! Package inputenc Error: Unicode char \u8:Γùî not set up for use with
LaTeX.

I read about using utf8x instead of utf8, but this package is incompatible to biblatex.

How can I solve this one?

EDIT: Thanks for all the responses and the various ways to draw circles! I should have mentioned that I need the circle to be combined with diacritic marks (see http://en.wikipedia.org/wiki/Dotted_circle ) – the result then looks like this:

◌̊

Thus, the XeLaTeX seems to be the way to go in my case.

As suggested in the comments, you could set your font to one that supports Unicode (this solution requires XeLaTeX):

\documentclass[12pt]{article}
\usepackage[a4paper]{geometry}
\usepackage{fontspec}

\setmainfont{Arial Unicode MS} % Other fonts that might work: Hiragino Maru Gothic Pro, Lao Sangam MN, Inaimathi, Microsoft Sans Serif

\begin{document}\huge

\noindent a b c \\
◌ \\
ä ë \\
à è \\
ç 

\end{document}

The inputenc package, even with the utf8 option doesn't load all the Unicode tables. It loads only those for which it knows it will have to typeset some glyphs.

You have then to teach the proper environment, because each Unicode block requires a different TeX fonts (they have only 256 characters).

So your example works with pdflatex, but modified into the following code.

\documentclass{article}
\usepackage[LGRx,T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[greek,english]{babel}
\usepackage{CJKutf8}
\begin{document}

\foreignlanguage{greek}{φΔδ}\begin{CJK}{UTF8}{gbsn}汉\end{CJK}

\end{document}

This is admittedly largely impractical for extensive usage of characters belonging to different blocks, so it may be advisable to switch to XeLaTeX or LuaLaTeX that can use OpenType fonts.

Important update

After release of Babel version 3.9, the LGRx encoding should not be used any more. Now LaTeX is able to interpret correctly UTF-8 characters for Greek out of the box, provided the Greek language is loaded with babel. So the example above becomes

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[greek,english]{babel}
\usepackage{CJKutf8}
\begin{document}

\foreignlanguage{greek}{φΔδ}\begin{CJK}{UTF8}{gbsn}汉\end{CJK}

\end{document}

If you make the following changes (and stick with biber), everything should work out just fine:

% \usepackage[utf8]{inputenc}
\usepackage{fontspec}

With fontspec you have a lot more font options anyway. I recommend typing texdoc fontspec at a terminal prompt (assuming you use TeX Live and aren't stuck on Windows).

An easy way to make your file compilable by either latex/pdflatex or lualatex would be (assuming no other packages are determining what you can or can't do):

\usepackage{ifluatex}

\ifluatex % LuaTeX
  \usepackage{fontspec}
  \defaultfontfeatures{Ligatures=TeX} 
  % load your system fonts; e.g.:
  \setmainfont{LinLibertineO}
  \setsansfont{LinBiolinumO}
  \setmonofont{Inconsolata}
\else % pdfTeX
  \usepackage[utf8]{inputenc}                   
  \usepackage[T1]{fontenc}
  % load some Type 1 font; e.g.:
  \usepackage[fulloldstylenums,largesmallcaps]{kpfonts}
\fi

Something similar could be done with the package ifxetex....
