+ * Checks if the trailing BiDi level should be used for an offset

+ * This method is useful when the offset is at the BiDi level transition point and determine

+ * Left-to-Right characters, R* denotes Right-to-Left characters.)
+ * Input (Logical Order): L1 L2 L3 R1 R2 R3 L4 L5 L6
+ * Input (Display Order): L1 L2 L3 R3 R2 R1 L4 L5 L6
+ *
+ * Then, think about selecting the range (3, 6). The offset=3 and offset=6 are ambiguous here
+ * since they are at the BiDi transition point. In Android, the offset is considered to be
+ * associated with the trailing run if the BiDi level of the trailing run is higher than of the
+ * previous run. In this case, the BiDi level of the input text is as follows:
+ *
+ * Input (Logical Order): L1 L2 L3 R1 R2 R3 L4 L5 L6
+ * BiDi Run: [ Run 0 ][ Run 1 ][ Run 2 ]
+ * BiDi Level: 0 0 0 1 1 1 0 0 0
+ *
+ * Thus, offset = 3 is part of Run 1 and this method returns true for offset = 3, since the BiDi
+ * level of Run 1 is higher than the level of Run 0. Similarly, the offset = 6 is a part of Run
+ * 1 and this method returns false for the offset = 6 since the BiDi level of Run 1 is higher
+ * than the level of Run 2.
+ *
+ * @returns true if offset is at the BiDi level transition point and trailing BiDi level is
+ * higher than previous BiDi level. See above for the detail.
