> java.text.Bidi returns directional runs (getRunStart(), getRunLimit(), getRunLevel()) in visual order if paragraph reading order is Right-to-Left (I mean the first run is at the end of character buffer, and the last is at the beginning).
> Consider the following test case:
> import java.text.Bidi;
> public class Test {
> public static final String LTR = "\u0061\u0062";
> public static final String RTL = "\u05DC\u05DD";
> public static final String newLine = "\n";
> public static final String defText = LTR + newLine
> + RTL + LTR + RTL;
> public static void main(String[] args) {
> Bidi bi = new Bidi(defText,
> Bidi.DIRECTION_DEFAULT_LEFT_TO_RIGHT);
>
> System.out.println("Runs: ");
> final int count = bi.getRunCount();
> for (int i = 0; i < count; i++) {
> System.out.println(i + ": " + bi.getRunLevel(i)
> + " [" + bi.getRunStart(i)
> + ", " + bi.getRunLimit(i)
> + "]");
> }
> }
> }
> The output on Harmony:
> Runs:
> 0: 0 [0, 3]
> 1: 1 [7, 9]
> 2: 2 [5, 7]
> 3: 1 [3, 5]
> The output on the RI:
> 0: 0 [0, 3]
> 1: 1 [3, 5]
> 2: 0 [5, 7]
> 3: 1 [7, 9]
