I have the following in a file, which I can then open with Vim.  I
just type the text I want above the corresponding row of capital
letters and execute the statement on the first line.  Vim then
populates the system clipboard with the corresponding letters in the
Unicode font.  I'm sure there are font-translator pages that would
make it a little easier, but I'd already done this.  Just adjust for
Emacs ;-)
