Writing Widmanstaetten

Professor Bhadeshia has some details about how to write Widmanstaetten on a webpage here.

In html the a umlaut character can be produced as below, you can find tables to look up various characters, such as this one, the ultimate authority on this being the w3c or whatever happens to work in your browser depending on your perspective.

ä — in html & # 2 2 8 ;

I’m naively hoping that is valid html, it seems to work in my browser and be allowed by wordpress. I did notice that the embedded videos from youtube are not standard html, at least not xml 1.0 compliant.

Anyway, it’s also fairly easy to produce this character in latex, it doesn’t even need the inclusion of any special packages, this simple example seems to work fine.

Example latex document using the a umlaut.

\documentclass[]{article}
\begin{document}
Widmanst\”atten
\end{document}
