\begin{document}
This is a test document showing how {\tt utf8.sty} makes it
possible to put many characters directly into a LaTeX document.
Digraphs in Vim exist for many of these characters, and
some additional bindings have been defined.
Thus, ← should look exactly the same as $\leftarrow$, and can
be typed like \verb.<-. inside Vim.
