Detailed Description

Reference implementation of the Unicode 3.0 Bidi algorithm.

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.

Input:
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.

1. unicode type array
2. unicode type array, with externally supplied base line direction

Output:
Output is separated into several stages as well, to better enable clients to evaluate various aspects of implementation conformance.

1. levels array over entire paragraph
2. reordering array over entire paragraph
3. levels array over line
4. reordering array over line

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.

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.

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.
