I showed one way to get tex commands based on the Unicode names of all
the characters in the cree  range here

It probably doesn't make sense to print off an entire font (normally)
there are rather a lot of characters:-) but it would be easy to have a
macro that took a range and a font and made a Unicode-style table in
the style of
