New Symbols for LaTex using Unicode

Hey all,

I am new to LaTex and I am trying to add a new symbol so that I can use it in my documents. I want to use unicode number 269B, an atom. How can I implement this in LaTex?

unicode symbols in LaTex

There are packages in LaTeX that will allow you to hand unicode input eg
"\usepackage[utf8]{inputenc}". But these really only provide a way of setting up handlers for the unicode characters; you still have to generate the output.

There are also packages aimed at specific languages (eg arabtex), but they typically work by using an ASCII mapping of the characters.

If you are doing a lot of unicode, it is worth looking at the XeTeX fork of TeX/LaTeX, found in many Linux distributions (and also for other OS). It allows you to easily load the newer font formats (such as TrueType), and work directly with unicode.

If you are just doing just one or two special character graphics, you could just bring it in as an image.

You will find a comprehensive list of LaTeX symbols and their fonts on the CTAN website.

If you have access to windows (xp/vista) fonts, the
symbol can be found in the webdings font
(distributed in windows xp/vista)

(you can display it in html with the code ⚛)

If you have a way of installing the true type font
to your system (Webding-Regular), then the next step
would be to download the texmf support files from

and you should be able to get your symbol as a font.

There's other possibility. I kinda remember there was
a tool called ttf2mf (works on ms-windows only) that
can output from a true type font the necessary metafont
sources. Then all you have to do is place the mf files
somewhere in your texmf tree (and update the database)
