TeX <-> Unicode mapping

[Markus Kuhn <Markus.Kuhn@cl.cam.ac.uk>]

For your enjoyment, here comes a UTF-8 plaintext file showing the
relationship between TeX characters and Unicode. It also shows a number
of plain-TeX characters missing in Unicode 3.0, namely the long arrows,
the epsilon variant, some of the n-ary operators, and the dot-less j.

The file is also available (along with other UTF-8 test and demo files)
on

  http://www.cl.cam.ac.uk/~mgk25/ucs/examples/

(Suitable X11 fonts for displaying it with xterm are as usual on
<http://www.cl.cam.ac.uk/~mgk25/ucs-fonts.html>)

TeX codes for various Unicode characters
