These tests examine the default behavior of characters against the expectations in the Unicode Standard Annex, version 5.1.0. The two-letter abbreviations are conventions for property names in the Unicode Standard. Non-tailorable characters have normative behavior in the Unicode Standard that applies in all normal circumstances.
For more information about expected line break behavior and line break classes, see Unicode Standard Annex #14 Line Breaking Properties.
