Most properties are stored in pretty much the same format in the UCD
files. UnicodeData.txt is the major exception; it seems to date from
when the set of properties was expected to be stable.

The big exception is set-valued properties.  PropList.txt can be viewed
as having an odd syntax for storing the set of miscellaneous Boolean
properties for which the codepoint has the value of 'true'.
