Well, as the Unicode web page says -- using Blocks to determine the
script is just, well, wrong.  (Or "inaccurate", if you want.)  So using
it will give both false positives and negatives.

In addition, that table assumes that each character belongs to a single
script, which is also wrong.  So I'm making a new table based on
Scripts.txt and ScriptExtensions.txt.
