Internal class used for Unicode character property database.

This classes store binary data read from uprops.icu. It does not have the capability to parse the data into more high-level information. It only returns bytes of information when required.

Due to the form most commonly used for retrieval, array of char is used to store the binary data.

UCharacterPropertyDB also contains information on accessing indexes to significant points in the binary data.

Responsibility for molding the binary data into more meaning form lies on UCharacter.
