The Unicode consortium provides a file containing annotations on many unicode
characters. This library contains a compiled version of this file so that
programs can access these data easily.

The library contains a very large (sparse) array with one entry for each unicode
code point (U+0000 - U+10FFFF). Each entry contains two strings, a name and an
annotation. Either or both may be NULL. The library also contains a (much
smaller) list of all the Unicode blocks.
