 * Currently, this means that both area First/Last and override lines are
 * tested against the properties from the API,
 * and the area boundary will not match and cause an error.
 *
 * This function should detect area boundaries and skip them for the test of individual
 * code points' properties.
 * Then it should check that the areas contain all the same properties except where overridden.
 * For this, it would have had to set a flag for which code points were listed explicitly.
