This comes from UnicodeData.txt, our source for the Unicode properties
of all the characters.  We parse it into uni-*.el files as part of the
build.

This comes from Unihan_Reading.txt, a different file that is part of
the Unihan database.

We don't currently have a property where to put this value, so we need
first to extend the properties.  And then we will need to parse the
above file and populate the property.  Patches welcome.  Bonus points
for reviewing other properties of the Unihan DB and adding whatever is
useful.  See UAX#38 (http://www.unicode.org/reports/tr38/), for the
description of the properties.

Thanks.
