[url] How to write URLs in Latex?

How do you write a URL in Latex?

The subscripts and everything else make the font look very strange when it compiles.

Here is all the information you need in order to format clickable hyperlinks in LaTeX:

http://en.wikibooks.org/wiki/LaTeX/Hyperlinks

Essentially, you use the hyperref package and use the \url or \href tag depending on what you're trying to achieve.

You just need to escape characters that have special meaning: # $ % & ~ _ ^ \ { }

So

http://stack_overflow.com/~foo%20bar#link

would be

http://stack\_overflow.com/\~foo\%20bar\#link

You can use \url

\usepackage{hyperref}
\url{http://stackoverflow.com/}

A minimalist implementation of the \url macro that uses only Tex primitives:

\def\url#1{\expandafter\string\csname #1\endcsname}

This url absolutely won't break over lines, though; the hypperef package is better for that.
