-/**
- * Reference implementation of the Unicode 3.0 Bidi algorithm.
- *
- * <p>
- * This implementation is not optimized for performance. It is intended
- * as a reference implementation that closely follows the specification
- * of the Bidirectional Algorithm in The Unicode Standard version 3.0.
- * <p>
- * <b>Input:</b><br>
- * There are two levels of input to the algorithm, since clients may prefer
- * to supply some information from out-of-band sources rather than relying on
- * the default behavior.
- * <ol>
- * <li>unicode type array
- * <li>unicode type array, with externally supplied base line direction
- * </ol>
- * <p><b>Output:</b><br>
- * Output is separated into several stages as well, to better enable clients
- * to evaluate various aspects of implementation conformance.
- * <ol>
- * <li>levels array over entire paragraph
- * <li>reordering array over entire paragraph
- * <li>levels array over line
- * <li>reordering array over line
- * </ol>
- * Note that for conformance, algorithms are only required to generate correct
- * reordering and character directionality (odd or even levels) over a line.
- * Generating identical level arrays over a line is not required. Bidi
- * explicit format codes (LRE, RLE, LRO, RLO, PDF) and BN can be assigned
- * arbitrary levels and positions as long as the other text matches.
- * <p>
- * As the algorithm is defined to operate on a single paragraph at a time,
- * this implementation is written to handle single paragraphs. Thus
- * rule P1 is presumed by this implementation-- the data provided to the
- * implementation is assumed to be a single paragraph, and either contains no
- * 'B' codes, or a single 'B' code at the end of the input. 'B' is allowed
- * as input to illustrate how the algorithm assigns it a level.
- * <p>
- * Also note that rules L3 and L4 depend on the rendering engine that uses
- * the result of the bidi algorithm. This implementation assumes that the
- * rendering engine expects combining marks in visual order (e.g. to the
- * left of their base character in RTL runs) and that it adjust the glyphs
- * used to render mirrored characters that are in RTL runs so that they
- * render appropriately.
