Character unit
Unicode character classification and conversion.
The character unit contains the TCharacter class,
which consists mainly of class functions. It should not be constructed, but
its class methods can be used. All class methods also exist as regular
methods.
Many routines depend on Unicode collation data to be present in the binary
(or distributed on disc with the application. This data can be loaded using the routines in
the unicodedata unit..
The FPC project distributes some Unicode collation data in .bco files which can be loaded
using the LoadCollation routine from that unit.
